Sinister is a death metal band from Rotterdam, the Netherlands, assembled in 1988, disassembled in 2003, and reassembled in 2005 by Adrie Kloosterwaard on vocals and Alex Paul on guitar. They have released nine albums.
The band split up in 2003. During that time, Aad and Alex formed a band called No Face Slave. The new material written for what was to be this band's debut was so similar to Sinister's style that after recruiting Bas on bass and Paul on drums, they decided to resurrect Sinister in 2005.
