List of Megadeth band members

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).

[3] After playing with various vocalists following Kane's exit, including Billy Bonds[4] and John Cyriis,[5] Mustaine ultimately took up lead vocals himself.

[2] 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.

[7] After years of problems stemming from substance abuse, Mustaine fired both Poland and Samuelson before recording the third album So Far, So Good...

[13] 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.

[12] 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.

[16] 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.

[19] While in rehearsal for the tour, newly returned drummer Menza once again parted ways with the band, as, according to Mustaine, he was unable to prepare for the physical demands of a full U.S.

[34] However, in November 2023, Kiko stated he would be extending his break, entering an indefinite hiatus,[35] while Mustaine confirmed that the band would go on with Mäntysaari as guitarist.
