Annihilator is a Canadian thrash metal/groove metal band founded by the vocalist, guitarist and bassist Jeff Waters. The band was formed in 1984 and is the highest selling heavy metal artist in Canadian history, although most of the sales have not been in the band's home country. Their first two studio albums, Alice in Hell and Never, Neverland, are considered masterpieces of Canadian heavy metal.
Since its inception, Annihilator has released thirteen studio albums and has undergone many line-up changes. The band now consists of two official members, with Waters on both guitar and bass and Dave Padden (who joined Annihilator in 2003) as a rhythm guitarist/vocalist. Since 2007, Waters and Padden have assembled a live band to perform with them.
