Anthrax is an American heavy metal band from New York City, formed in 1981. Founded by guitarists Scott Ian and Danny Lilker, the band has since released ten studio albums and 20 singles, and an EP featuring Public Enemy. The band was one of the most popular of the 1980s thrash metal scene. When thrash metal began to gain a major following in the mid-to-late 1980s, Anthrax were dubbed one of the "big four" of thrash metal alongside Metallica, Megadeth, and Slayer. They were also one of the early thrash metal bands to sign to a major label (Island Records, in 1985).
The band lineup has been changed numerous times; following the departure of drummer Dave Weiss and bassist Kenny Kushner, several musicians replaced both band members' roles, though Paul Kahn and Greh Walls were the first to do so. In addition to this aspect, there were multiple vocalists involved in Anthrax, with Neil Turbin, Joey Belladonna and John Bush being among the frontmen of the band. Scott Ian and Charlie Benante are the only constant members that appear on every album. Bassist Frank Bello has played on every album with exception of the band's debut.
