Montreal band Arcade Fire thrilled nearly 10,000 fans with a free concert Wednesday night in a South Shore shopping mall parking lot.

Band members crowded together on a rented stage assembled at the outer edge of the Place Longueuil parking lot, a stone's throw from the Jacques-Cartier Bridge.

They played a mix of new and old songs, including Rococo and Modern Man, two recently released tracks from their upcoming album Suburbs.

The crowd also heard older hits like Neighbourhoods #1 (Tunnels), Rebellion, Intervention and Haiti.

The short show wrapped at 9:30 p.m. with a two-song encore (Keep the Car Running and Wake Up ).

Quebec police were highly visible at the show, with officers directing hordes of concert-goers through the maze of overpasses that surround the shopping centre.

The band says it will play two shows at Toronto's Danforth Hall this weekend.
