Muhammed Suiçmez Putrefaction" was released on Noise Solution Records (1999). Following the breakup of Necrophagist, Suiçmez currently works as an engineer at BMW.

Suiçmez also had a 27 fret 7 string custom Ibanez, as seen on photos on his band's MySpace, but it was ruined when someone mishandled it backstage after a show.
