Arcade Fire's Win Butler and Regine Chassagne have collaborated with New Orleans' Preservation Hall Horns and Haitian group RAM on a new song titled "Ann Ale! (Let’s Go!)." You can stream it below. The song is in celebration of Krewe Du Kanaval, a Mardi Gras Krewe formed by Win, Regine and the Preservation Hall. It's the first new Krewe to join Mardi Gras in five years. As they explain on their website, "'Kanaval' is the Haitian Creole word for the celebration before Lent. In New Orleans, it is the period leading up to Mardi Gras." Says Preservation Hall's Ben Jaffe:

For many years my wife, Jeanette and I have wanted to celebrate Mardi Gras in a unique way that reflected our reverence for the spiritual side of this unique holiday. We had wanted to do something in Congo Square that was inclusive and representative of modern New Orleans, of post-Katrina culture. Through Win & Regine, we discovered the deep cultural connections between Haiti and New Orleans and Krewe du Kanaval is our way of expressing our the mutual love and respect for these two beautiful cultures.

The Kanvale event takes place on Tuesday, February 6 at Congo Square and includes a grand procession through Treme in the afternoon, a free block party, and the "Rhum and Drums" Kanaval Ball benefit at One Eyed Jacks that night featuring Preservation Hall Jazz Band (with members of Arcade Fire), Pierre Kwenders, DJ Cosmo Gonik, DJ Windows98, Paul Beaubrun of Boukman Eksperyans, plus special musical guests from Haiti.All Proceeds benefit the Preservation Hall Foundation and Chassagne’s KANPE. nonprofit organization and there's more information is here.
