Arcade Fire may have raised the profile of Canadian rock this year but Broken Social Scene were a major influence on them. An 18-musician collective gathered from little-known Canuck bands, they won a Juno - the Canadian equivalent of a Brit - for their 2003 album, You Forgot It in People.

A mere 11 of them have made it over for this tour to promote their self-titled third album, but they are quite an ensemble: the tiny stage boasts five beards and a tartan deerstalker. To the side, trombonists and violinists queue patiently.

Yet when they fire into life, Broken Social Scene are a feast of frenetic, euphoric music. Their forte is an evocative, giddy neo-psychedelia with elements of post-rock, funk and blues, but such tidy categorisation is lost in their visceral thrill.

Fire Eye'd Boy is an explosion of plangent yet hyperventilating rhythms, like Flaming Lips gripped by a profound joy. Ibi Dreams of Pavement is as expansive as Brian Jonestown Massacre, but with that band's narcotic fug transmuted into sunny positivity.

Charismatic vocalist Kevin Drew lends a Prince falsetto to Hotel, and the soulful Major Label Debut is so well received that, 10 minutes after playing it, they play it again.

It's unclear if Broken Social Scene will survive in this format - Drew wants to work with a smaller unit, and there is wry on-stage banter about whether British dates in February will be fulfilled. But even if this Scene is to rip asunder, this was very special.
