Not only are Arcade Fire gearing up to release their anticipated new album WE next week, Win Butler and Régine Chassagne also appear on a song by fellow Canadian artist Pierre Kwenders' new album José Louis And The Paradox Of Love, which came out today via Arts & Crafts. Win sings and Régine plays keys on the album's nine-and-a-half minute opener "L.E.S (Liberté Égalité Sagacité)," a thumping dance track that also features production by King Britt. Win comes in about halfway through with sort of a muttered, repeated delivery that suits this kind of song very well. Listen and stream the full album below.
