Broken Social Scene is a Canadian indie rock band, a musical collective including as few as six and as many as nineteen members, formed by Kevin Drew and Brendan Canning. Most of its members play in various other groups and solo projects, mainly in the city of Toronto. These associated acts include Metric, Feist, Stars, Apostle of Hustle, Do Make Say Think, KC Accidental, Emily Haines & The Soft Skeleton, Amy Millan, and Jason Collett.

In June 2009, the band played a short set to launch This Book Is Broken at the North by Northeast festival. They played a mix of new songs from their then-upcoming album and old favourites, and were joined by Feist, who also joined them on their second visit to Mexico City in October.  During the band's free performance at the Harbourfront Centre on July 11, 2009, they were joined by nearly all past contributors, including Feist, Emily Haines and James Shaw, Amy Millan and Evan Cranley, John Crossingham, Jason Collett and Julie Penner. This revue-like show celebrated other projects by members as well as including material from the then-upcoming album. Emcee Bruce McDonald announced the filming of a documentary directed by him and written by Don McKellar, Titled This Movie Is Broken, it includes concert footage and a fictional romance. Although McDonald announced at the concert that film submitted by fans would be used in the movie, the final cut of the movie included only one submission, a front-row recording of "Major Label Debut".  Broken Social Scene released their fourth full-length album on May 4, 2010. Entitled Forgiveness Rock Record, it was recorded at Soma in Chicago, with John McEntire producing, and in Toronto at the studio of Sebastian Grainger and James Shaw. For the first time, Amy Millan, Emily Haines, and Leslie Feist recorded a track together (albeit at different times). This album was short-listed for the 2010 Polaris Music Prize.  In August 2010, Broken Social Scene initiated their "All to All" remix series, which included seven different versions of the track from Forgiveness Rock Record. Every Monday a new remix was released and available for 24 hours via a different online partner. The first version, "All to All (Sebastien Sexy Legs Grainger Remix)", by Sebastien Grainger, was released August 9 via Pitchfork.
