Originally intended to be a technical death metal band, Exsanguination evolved to the point that the name no longer suited the music. Dissolution was decided upon after many name considerations, as it suited the new style of technical progressive death metal.

After a year of searching and many let downs, Troy Lajoie was found to fill the drumming position.Shortly after, Shane Guy was found to fill in the bass, complimenting the band in it's fullest respects.

After some unsucessful attepts at jamming, Shane was replaced by Graeme Martin, now a permanant member of the band. Troy and Dissolution shortly after parted ways and Dave Boyle was added as the new drummer. After reliability issues and interventions, Dave decided to leave Dissolution just weeks before two big shows. Our good friend Robot Drummer came to the rescue, and both shows went off with little issues. Scott Patterson has finally stepped up and proven there actually was a drummer who could fillthe boots of the machine like previous drummer, Robot Drummer. Finally, a drummer we don't have to plug in!

In 2007, Graeme decided to move to Burlington, On and the search for a new bassist was on.

Jean-Louis Wittinger (formerly of Fuck The Facts and currently of local grindcore act Putrescence) was recruited in late-2007 to handle bass duties, providing a solid foundation for Dissolution once again.

In mid-2008, Dissolution began writing the follow-up to 2007's "Dying. Dead. Undead.", and in the process of doing so released a 3-song demo.

Due to scheduling conflicts, Jean-Louis Wittinger had to part ways with Dissolution in Early 2009.

With the addition of Matt Stanicky to fill the bass position in mid-2009, Dissolution began work on their as-of-yet untitled sophomore album, eyeing a release date sometime in early 2011.
