Members also had a side-project called Puhelinkoppi (playing some kind of hardcore-punk-metal combination with really offensive lyrics towards everything), which is better known in general in Finland than Convulse itself.
The band was previously known as S.D.S. and played speed metal, releasing a demo tape called ‘Mental Genocide Demo II 4/90″.
Rami Jämsä recorded with the hard rock band Havoc, 7 inch “Passage in My Life/Surrounded by Bain” in 1989.
