Sinister was formed in 1989. It was the time when such style of music like death metal was just at the very beginning of its development. The band debuted in 1991, and since that time and up to 1998 they released five albums. In 1998 the band made a decision to leave the label, and sign a contract with another one called Hammerheart Records.
As soon as Sinister signed the contract with Hammerheart Records their stuff a bit changed: in 1999 one more singer joined the band called Rachel. It was treated as one of the strengths of the band to have a female vocalist as a singer. Together with Rachel the band released one more album in 2001 which was called Creative Killings.
