Megadeth were formed in 1983 when lead singer Dave Mustaine left the group Metallica. Throughout the 80s and 90s, Megadeth achieved massive success with their distinctive brand of thrash metal mixed with aggressive lyrics.
Classic albums such as Killing Is My Business...And Business Is Good and Peace Sells...But Who's Buying firmly established the band as legitimate contenders for the 80s metal crown before struggling with drink and drug addiction.
Once clean however, the band enjoyed their biggest success in the early 1990s with the more mainstream-rock sounds of Countdown To Extinction. Since then they have released a number of popular albums, such as Youthanasia, Cryptic Writings and The World Needs A Hero, whilst retaining their powerful live sound.
