Starting in 1988 or possibly 1989, Sinister was a band arising in the middle of the Death metal hype. After releasing a demo, wich sold about 1 500 copies, a promo tape followed. Sending out the promo to various labels resulted in signing up at Nuclear Blast Records, Germany 1991.
Their debut CD "Cross the Styx" saw the light in early 1992, and sold many copies worldwide. Many liveshows all over Europe followed. Touring with bands like Suffocation, Cannibal Corpse and Deicide increased the number of people knowing Sinister.
In the years after that, Sinister succeeded in maintaining their popularity by releasing their second album "Diabolical Summoning" (1993), "Hate" (1995) and doing many live shows all over Europe and a very successful 55 show-tour through all the USA.
At the end of this period, Death metal got less popular, lots of Death metal fans switched over to Black metal, Gothic and other atmospherical music. Sinister never thought about playing other music than their favourit; Death metal. Some years past and the band released their mini-CD "Bastard Saints" (1996), and played a few live-shows. Several line-up changes followed, and led Sinister to write their most aggressive brutal and intens album so far "Agressive Measures" (1998).
This time their maintenance in Death metal payed off. Death metal is back, where for Sinister it never left. The response from fans and critics where good, sold lots of albums and played lots of good shows, of wich a short US-tour and good festivals like Wacken Open Air, Milwaukee Metalfest and Chech Dynamo blessed their way. Yet the cooperation between Sinister and vocalist Eric didn't work out very well, wich lead to Eric's departure in August 1999. After him, Joost from Inhume also took care of the vocal duties for a while until Sinister finally found a (female!) singer in Rachel (also from Occult), who also features on their latest masterpiece of brutality, "Creative Killings".
On April 17th, 2004, the band officially announced that they had split up as drummer Aad Kloosterwaard found it too difficult to continue combining the band and his day job. On April 27th, 2005, their label Nuclear Blast officially announced that the band had reunited with a revamped line-up after numerous letters and e-mails from fans around the world.
