Anthrax is an American thrash metal band and one of the "Big Four" of thrash, alongside Metallica, Megadeth, and Slayer. Formed in 1981 in New York City by Scott Ian and Dan Lilker, the band is known for their aggressive riffs, high-energy performances, and a signature blend of thrash, heavy metal, and hardcore punk influences. Albums like Among the Living (1987) and Persistence of Time (1990) helped define their sound, featuring socially conscious lyrics and a mix of intensity and humour. Anthrax has remained a driving force in metal, evolving their style while staying true to their roots.
