Broken Social Scene is a Canadian indie rock band, a musical collective including as few as six and as many as nineteen members, formed in 1999 by Kevin Drew and Brendan Canning. Most of its members currently play in various other groups and solo projects, mainly based around the city of Toronto. The band refuses the label "supergroup", based on size or the ubiquity of their members, claiming that in the indie scene everyone is involved in more than one project.
The group's sound could be considered a combination of all of its members' respective musical projects, and is occasionally considered baroque pop. It is characterized by a very large number of sounds, grand orchestrations featuring guitars, horns, woodwinds, and violins, unusual song structures, and an experimental, and sometimes chaotic production style from David Newfeld, who produced the second and third albums.
In 2009, Stuart Berman's This Book Is Broken, which details the band from its inception to its critical acclaim, was published. In 2010, Bruce McDonald made This Movie Is Broken, a movie about the band's Harbourfront show during the 2009 Toronto strike.
