MONTREAL – Montreal music industry executives, critics and even Canada's prime minister on Monday all sang the praises of Arcade Fire, saying its Grammy win was a coup for the city's burgeoning music scene.

The Montreal-based indie group won the best album Grammy on Sunday for their record "The Suburbs," at the music industry's annual awards show in Los Angeles.

Its latest record had been up against "The Fame Monster" by Lady Gaga, "Recovery" by Eminem, "Need You Now" by Lady Antebellum and "Teenage Dream" by Katy Perry on the best album shortlist.

"These awards... are a testament to a thriving Canadian music industry," Prime Minister Stephen Harper said in a statement.

Arcade Fire, which formed in 2000, gained tremendous international recognition last year, but this was its crowning achievement, said Marc Cassivi, a columnist for Montreal's French-language daily La Presse.

"They're the standard bearer for the musical effervescence of the decade," firmly rooted in Montreal, he told AFP, noting that the group's leader Win Butler thanked the Canadian metropolis when he accepted the award.

"Others may have thanked God, their manager or their parents," Cassivi said, while Butler "thanked Montreal for its burgeoning music scene, other local artists, the opportunity to live in a major city where rents are still affordable and where creativity abounds."

"It's a city that inspires, where there is a lot of art, and it influences musical composition," explains Eli Bissonnette, head of independent music label Dare to Care.

This Grammy "gives another nod" to Montreal's music scene, which is "already recognized throughout the world," he said. "It paves the way for more Canadian acts in the United States."
