Exhale was founded in the summer 2004 by guitarist Johan and drummer Gustav. They started to write songs together and finally they went in to a studio to record some hard grinding tracks. The studio engineer Ulf took place as a vocalist and Karl was brought in to handle the bass. Three tracks were recorded and finally released as "...die inside" in august the 4th. Late 2004 new bass player Johan is added to the lineup

Spring 2005 Exhale made a bunch of live performances and agreed to record a full-length album for Acoustic Trauma Recordings. That deal was eventually broken beacause of some personal problems at the label. Later on 2005 Exhale signed with Emetic Releases to release this album and "Prototype" was released early 2006.

Soon after, Ulf quits and new vocalist Peter joins.

After touring Europe in 2006 and visiting the US in 2007 writing a new album begins. Viktor joins as a second guitarist and quits soon after. Andreas proves to be up for the job. Late spring 2008 recording the unnamed album is finished.
