Return of the Killer A's  Return of the Killer A's is a best of compilation album by the heavy metal band Anthrax, released in 1999. The cover of "Ball of Confusion" features Anthrax's first new recording with former lead singer Joey Belladonna since 1991, and their first with former bassist Dan Lilker since 1984. Neither one would stay with the band past that song's recording, though a tour featuring both Belladonna and then-current Anthrax singer John Bush was in the works at one point. The song is also notable because it features both Belladonna and Bush on vocals. The album included at least one song from all but their debut studio album, "Fistful of Metal", up to the point of the disc's release in 1999. Also included is the track taken from two EPs and "Bring the Noise", a Public Enemy remix featuring Anthrax previously released on "Attack of the Killer B's", the compilation of B-sides. Two singles were released from "Attack of the Killer A's":
