Formed in 1988 under the name S.D.S., Convulse's first release was the "Resuscitation of Evilness" demo cassette in 1990. The success of the demo led to a deal with the French record label Thrash Records, which released the band's first full-length album, "World Without God". A CD-single, "Lost Equilibrium", followed in 1993 via Relapse Records, after which Convulse prepared to record its second album, "Reflections". The group travelled to Sunlight Studios in Sweden and laid down the effort in a one-week period. The following year (1993) was dedicated to Convulse members performing their mandatory military service in Finland, which delayed the release of "Reflections" until the summer of 1994 (also through Relapse). An attempt to regroup in support of the CD ended "with poor results," and after serious discussions, a decision was made to put Convulse to rest.
After an 18-year break, Convulse returned in 2012 and played a few comeback shows in Finland. In addition, the band has already been confirmed to play next year's edition of the Maryland Deathfest, with more live appearances in the works.
