Destroyalldreamers was a Canadian four-piece instrumental post-rock band from Montreal consisting of guitarists Eric Quach and Mathieu Grisé, drummer Shaun Doré and former bassist Michèle Martin. Their sound has often been described as a mix of classic '90's shoegazing with Godspeed You! Black Emperor-like aesthetics. They released two full-length studio albums, both of them on Montreal's independent record label Where Are My Records.
The quartet is known for their extensive use of effects pedals and for mixing elements of shoegaze, wall of sound and post-rock, which has had many fans categorize them as post-shoegaze. Although the group has shown interest in recording new material, they have been inactive since 2007 with its members pursuing other projects.
