Arcade Fire and Celine Dion are joining forces.

No, it's not a masterplan to destroy hipster minds everywhere. Rather, the pair will be part of a good cause -- a benefit concert to support the family of Denis Blanchette, a lighting technician who was shot and killed at a victory party earlier this month when the separatist Parti Québécois won the provincial election in Quebec.

Blanchette was shot when Richard Henry Bain opened fire during Quebec's premier-designate Pauline Marois' speech. Bain has been charged with murder.

Where the artists come in is the Denis Blanchette Benefit Concert, being held October 1 at Metropolis in Montreal, Quebec. The funds raised will go towards providing for Blanchette's young daughter as well as co-worker Dave Courage, who was also shot, but survived.

Arcade Fire and Celine Dion have already committed to performing, but a number of other high profile Quebec musicians are also playing as well, including Patrick Watson, Coeur De Pirate, Ian Kelly and Vincent Vallières. Organizers are also suggesting there may be other surprise guests.

Tickets will go for between $80 and $175 and can be purchased through Ticketmaster.
