Overkill is an American thrash metal band formed in 1980 in New Jersey. The band has been active since 1984, releasing 16 studio albums, 2 EPs, 2 live albums and a "covers" album. Despite their first album being released in 1985, most of the songs appearing on their first two albums were written between 1981 and 1984, and as such, they are sometimes hailed as the inventors of thrash metal. The band also has a notable mascot (named Chaly), a skeletal bat with a skull-like face, bony wings, and green eyes. Read more about Overkill on Last.fm.
