Formed in 1981 by guitarist Scott 'Not' Ian and bassist Dan Lilker (later in Nuclear Assault, S.O.D., Brutal Truth), Anthrax is one of the pioneers of the thrash metal scene from the 80's, along with the "rest of the big four": Metallica, Megadeth and Slayer. This radio broadcast from Dallas' Z-rock radio station from July 1989 shows the band at the top, and features a great set of their early classics along with inspired covers of Sex Pistols and Judas Priest.
