Feather Disperse and Affekt Pendule were the only releases Suppurate System ever released. They did do a song on the Remix Album of Providence of Decadence though.
Well I mainly like their songs with a basic song structure like Affekt Pendule, Tranceluscence, Providence and flowers fall on your cheeks. Except that, the rest of the songs are pretty much hit and miss and some songs on Feather Disperse are basically just annoying. Did you listen to Affekt Pendule (the song) and Providence?
