DUTCH COLLISION
Collision is an aggressive grindcore band with metal and hardcore influences. What you get is a violent straight-in-your-face wall of sound that swings. Combined with two singers, to give it something extra, especially live.
The band was founded by singers Björn and Tammi in 2000. After getting the right line-up together, the band started playing blasting live shows, full of energy and aggression.
After many live shows and one demo (“Miserable, squashed, dead”) Collision recorded their first full length album called “Romantic display of love”, which was released in 2003 on Bizarre Leprous Production.
In 2005 Bass player Marcel was replaced by Mangled bass player Boris.
At the end of 2005 the band recorded a new album called “Roadkiller”. The album is released in June 2006 by Bones Brigade Records and contains 14 songs of grinding thrashcore assault!
Collision has done some great gigs with bands like: Pungent Stench, Saxon, Gorerotted, Agathocles, Sanitys Dawn, Inhume, After Forever, Suppository, Mangled, Gojira, Aborted, Sinister and more.Collision also played on festivals like Obscene Extreme (Czech Republic), Fit Of Rage (Czech Republic), Weistock (Holland), Rockweekend (Holland) and more.

SWEDISH COLLISION
A group of childhood friends, Collision perfected their craft for years before releasing their dark, sludgy and heavily Led Zeppelin influenced harmonies onto the general public.
Nik Chinboukas (vocals/guitar), Gustavo J. Vitureira (bass) and Alex Kyriazis (drums) toiled in obscurity in the New York club scene for some thirteen years before one of their demos finally caught the attention of Chaos/Columbia. The band insisted on recording and producing their self-titled debut in their own recording studio. The album was innovative and defied categorization, while the single "Chains" managed to get some limited airplay.
By 1995 the grunge movement was in full swing and Collision compromised their sound to release the disappointing Coarse album. The band broke up but would later reform as Kollizion for a short time. Chinboukas is currently a sought after producer in New York while Kyriazis has done some session work with bands such as The Beatnuts.

AMERICAN COLLISION
During the late 90's/early 2000's Southern California had the Hardcore (punk) band Collision. Playing fast and straight forward they combined a sound somewhere between Minor Threat and Gorilla Biscuits; fitting in nicely among contemporaries In My Eyes & the Nerve Agents.
They released a 7inch on Ambassador records, CD EP on Ambassador, and a final demo in 2001 before breaking up. Members went on to many bands, including Impact/Stand And Fight, Internal Affairs, and One Choice.
In 2007 it was announced the band intended to reunite and play, but as of late 2008 this hasn't happened- among other things, a drummer couldn't be found to play.
