Megadeth is an American thrash metal band formed by guitarist/vocalist Dave Mustaine after he was fired from Metallica. The first line-up, in 1983, after their name change from Fallen Angels, featured Mustaine and Robbie McKinney on guitar, vocalist Lor Kane and bassist Matt Kisselstein. The band's current line-up includes consistent member Mustaine, bassist James LoMenzo (2006 to 2010, and since 2021), drummer Dirk Verbeuren (since 2016) and guitarist Teemu Mäntysaari (since 2023).

History

The original Megadeth lineup was short-lived; Lor Kane, the band's first vocalist, would soon leave the group,{{Cite web|last=Brannigan|first=Paul|date=June 12, 2019|title=Megadeth’s Killing Is My Business: hamburgers, heroin and one of metal’s greatest debut albums|url=https://www.loudersound.com/features/megadeth-story-of-killing-is-my-business|access-date=February 14, 2025|work=Metal Hammer|language=en|archive-date=April 7, 2023|archive-url=https://web.archive.org/web/20230407035043/https://www.loudersound.com/features/megadeth-story-of-killing-is-my-business|url-status=live}} (though he did sing on the groups 1983 demo).{{cite journal|url=https://thecorroseum.org/fanzines/whiplash-usa-01.php|work=Whiplash|date=1983|title=Megadeath|volume=1|access-date=March 16, 2025|page=4|archive-date=December 24, 2022|archive-url=https://web.archive.org/web/20221224213233/https://thecorroseum.org/fanzines/whiplash-usa-01.php|url-status=live}} The band's first bassist, Matt Kisselstein,{{cite web|url=https://ultimateclassicrock.com/dave-mustaine-metallica-fired/|title=Dave Mustaine After Metallica: 40 Moments for 40 Years|work=Ultimate Classic Rock|last=Kielty|first=Martin|date=April 11, 2023|access-date=February 14, 2025|archive-date=October 2, 2023|archive-url=https://web.archive.org/web/20231002122553/https://ultimateclassicrock.com/dave-mustaine-metallica-fired/|url-status=live}} was replaced by Minnesotan David Ellefson{{Cite web |title=David Ellefson Talks How Dave Mustaine Treated Him When They Met, Recalls What He Had to Say About Metallica |url=https://www.ultimate-guitar.com/news/general_music_news/david_ellefson_talks_how_dave_mustaine_treated_him_when_they_met_recalls_what_he_had_to_say_about_metallica.html |access-date=February 16, 2025 |website=Ultimate Guitar |language=en |archive-date=December 4, 2023 |archive-url=https://web.archive.org/web/20231204075712/https://www.ultimate-guitar.com/news/general_music_news/david_ellefson_talks_how_dave_mustaine_treated_him_when_they_met_recalls_what_he_had_to_say_about_metallica.html |url-status=live}} and guitarist Robbie McKinney was replaced with Minnesotan Greg Handevidt (who was Ellefson's roommate).{{cite web|last=Zeiler|first=Millie|title=10 Guitarists Who Departed Before Their Bands Became Famous|url=https://classicrock.teamrock.com/news/2014-11-26/megadeth-chris-broderick-shawn-drover-quit|work=Classic Rock History|date=October 11, 2023|access-date=March 16, 2025}} After playing with various vocalists following Kane's exit, including Billy Bonds{{cite web|url=https://www.revolvermag.com/music/8-things-you-didnt-know-about-megadeths-killing-my-business-and-business-good/|title=8 Things You Didn't Know About Megadeth's 'Killing Is My Business… And Business Is Good'|work=Revolver|date=June 12, 2018|access-date=February 17, 2025}} and John Cyriis,{{cite web|url=https://bravewords.com/news/agent-steel-founder-vocalist-john-cyriis-on-briefly-joining-megadeth-dave-mustaine-was-not-prepared-to-launch-the-first-album-with-my-lyrical-subjects|title=Agent Steel Founder/Vocalist John Cyriis On Briefly Joining Megadeth - 'Dave Mustaine Was Not Prepared To Launch The First Album With My Lyrical Subjects'|work=Brave Words & Bloody Knuckles|date=October 24, 2019|access-date=February 24, 2023|archive-date=May 13, 2022|archive-url=https://web.archive.org/web/20220513032247/https://bravewords.com/news/agent-steel-founder-vocalist-john-cyriis-on-briefly-joining-megadeth-dave-mustaine-was-not-prepared-to-launch-the-first-album-with-my-lyrical-subjects|url-status=live}} Mustaine ultimately took up lead vocals himself. Megadeth recorded Last Rites, a three-song demo, in 1984, which featured drummer Lee Rauch and Ellefson. Slayer guitarist Kerry King covered live dates at Ruthie's Inn and The Stone in February and April 1984 while a permanent replacement was sought. Jazz fusion drummer Gar Samuelson would go on to join the band. After playing a few shows as a three-piece, guitarist Chris Poland also joined.{{cite web|last=Doe|first=Bernard|title=Megadeth – Love It To Death|url=http://www.metalforcesmagazine.com/site/feature-megadeth-mf12/|work=Metal Forces|date=December 1985|access-date=April 18, 2024|archive-date=October 2, 2013|archive-url=https://web.archive.org/web/20131002123451/http://www.metalforcesmagazine.com/site/feature-megadeth-mf12/|url-status=live}} During Megadeth's 1985 tour promoting their debut album, Killing Is My Business... and Business Is Good!, Poland left the band and was temporarily replaced by Mike Albert.{{cite web |title=Timeline of the band's history|url=http://www.megadeth.com/history.php|url-status=dead|archive-url=https://web.archive.org/web/20090315085359/http://megadeth.com/history.php |archive-date=March 15, 2009 |access-date=March 1, 2009 |publisher=Megadeth.com}} On the tour, Mustaine offered the drummer position to Exciter drummer Dan Beehler, though he declined the offer.{{cite web|url=https://bravewords.com/news/during-exciters-heyday-dan-beehler-was-asked-to-join-megadeth-and-venom|title=During Exciter's Heyday, Dan Beehler Was Asked To Join Megadeth And Venom!|date=November 5, 2005|access-date=January 30, 2024|work=Brave Words & Bloody Knuckles|archive-date=October 19, 2021|archive-url=https://web.archive.org/web/20211019191757/https://bravewords.com/news/during-exciters-heyday-dan-beehler-was-asked-to-join-megadeth-and-venom|url-status=live}} Poland then rejoined Megadeth in October of the same year, shortly before they began work on Peace Sells... but Who's Buying? After years of problems stemming from substance abuse, Mustaine fired both Poland and Samuelson before recording the third album So Far, So Good... So What! Poland was initially replaced by Jay Reynolds, who proved unable to perform the solos in-studio and was replaced by Jeff Young, his guitar instructor.{{cite web|url=https://ultimateclassicrock.com/megadeth-so-far-so-good-so-what/|title=Why Megadeth Struggled Through ‘So Far, So Good … So What!’|work=Ultimate Classic Rock|date=January 19, 2018|access-date=September 8, 2023|last=Christopher|first=Michael|archive-date=September 19, 2023|archive-url=https://web.archive.org/web/20230919231523/https://ultimateclassicrock.com/megadeth-so-far-so-good-so-what/|url-status=live}} Samuelson was replaced in 1987 by Chuck Behler, who was his drum tech.{{cite web|url=https://www.invisibleoranges.com/30-years-of-megadeth-drummers-a-guide/|title=30 Years of Megadeth Drummers: a Guide|date=May 30, 2015|access-date=November 30, 2023|work=Invisible Oranges|archive-date=December 2, 2023|archive-url=https://web.archive.org/web/20231202170809/https://www.invisibleoranges.com/30-years-of-megadeth-drummers-a-guide/|url-status=live}}

During their world tour in support of So Far, So Good... in February 1988, Mustaine noticed problems developing with Behler.{{cite web|url=http://megadeth.rockmetal.art.pl/articles_hotmetal1990.html|title=The Big Four|last=Doreian|first=Robyn|date=September 1990|work=Hot Metal Magazine|access-date=March 1, 2009|archive-date=February 25, 2012|archive-url=https://web.archive.org/web/20120225120429/http://megadeth.rockmetal.art.pl/articles_hotmetal1990.html|url-status=dead}} Six months later, Mustaine fired both Behler and Young.{{cite web|url=https://www.allmusic.com/artist/p4885|title=Megadeth Biography|last=Erlewine|first=Stephen Thomas|work=AllMusic|publisher=TiVo Corporation|access-date=March 1, 2009|archive-date=April 9, 2011|archive-url=https://web.archive.org/web/20110409214644/http://www.allmusic.com/artist/p4885|url-status=live}} In July 1989, Nick Menza was hired to replace Behler on the drums. After a lengthy search for a new lead guitarist, Megadeth enlisted Marty Friedman, who officially joined in February 1990.{{cite web|url=http://megadeth.rockmetal.art.pl/interviews_practisingmusician1990.html|title=A Founding Forefather of Thrash|last=Stix|first=John|year=1990|work=Guitar for the Practicing Musician|access-date=March 1, 2009|archive-date=February 14, 2012|archive-url=https://web.archive.org/web/20120214232012/http://megadeth.rockmetal.art.pl/interviews_practisingmusician1990.html|url-status=live}} The lineup remained unchanged for almost eight years, until Menza discovered a tumor on his knee, which forced him to leave the tour to undergo surgery. He was replaced by Jimmy DeGrasso, temporarily at first. Following the Ozzfest tour in 1998, however, DeGrasso replaced Menza permanently, after Mustaine claimed that Menza had "lied about having cancer".{{cite web|url=http://megadeth.rockmetal.art.pl/interviews_rockmetal2001.html|title=An Ugly American|date=March 2001|access-date=March 1, 2009|archive-date=February 14, 2012|archive-url=https://web.archive.org/web/20120214232254/http://megadeth.rockmetal.art.pl/interviews_rockmetal2001.html|url-status=live}} Following the release of Risk, the band began a new world tour in September 1999. Three months into the tour, Friedman announced that he would be leaving the band, citing "musical differences". Megadeth enlisted guitarist Al Pitrelli as Friedman's replacement in January 2000. In early 2002, Mustaine suffered several injuries, which led him to announce in a press release that Megadeth had disbanded.{{cite press release|title=Dave Mustaine suffers serious injury, announces departure from Megadeth; Group disbanding after nearly 20 years together|publisher=Megadeth.com|date=April 3, 2002|url=http://www.megadeth.com/news/pr/disband.html|access-date=January 6, 2009|url-status=dead|archive-url=https://web.archive.org/web/20061021225745/http://www.megadeth.com/news/pr/disband.html|archive-date=October 21, 2006}} Following nearly a year of recovery, Mustaine began work on what was to be his first solo album. The new material was recorded with session musicians Vinnie Colaiuta and Jimmy Lee Sloas, but the project was put on hold when Mustaine agreed to remix and remaster Megadeth's eight-album back catalog with Capitol Records.

In May 2004, Mustaine returned to his newest recordings, intended as a solo effort, but because of outstanding contractual obligations with the band's European label EMI, he was forced to release one more album under the "Megadeth" name.{{cite web|url=http://www.hardradio.com/shockwaves/mustaine6.php3|title=Dave Mustaine Interview, Pt. 6|last=Nalbandian|first=Bob|publisher=HardRadio|access-date=October 7, 2008|archive-date=March 18, 2016|archive-url=https://web.archive.org/web/20160318214817/http://www.hardradio.com/shockwaves/mustaine6.php3|url-status=live}} Mustaine decided to reform the band, and contacted the Rust in Peace line-up to re-record backing tracks on his latest songs. While drummer Nick Menza initially signed on, Marty Friedman and David Ellefson were both unable to come to an agreement with Mustaine.{{cite web|url=http://www.hardradio.com/shockwaves/mustaine2.php3|title=Dave Mustaine Interview, Pt. 2|last=Nalbandian|first=Bob|publisher=HardRadio|access-date=October 7, 2008|archive-date=January 1, 2010|archive-url=https://web.archive.org/web/20100101105031/http://hardradio.com/shockwaves/mustaine2.php3|url-status=live}} Chris Poland was hired by Mustaine to contribute guitar solos for the new album. This marked the first time since the Rust in Peace demos that the two musicians had worked together.
