The duo Cassius, fresh off a successful first album, 1999, released their second album, Au Rêve, in early fall. Zdar and Boombass were originally a part of the French Touch movement but wanted to explore new genres, produce real songs, and, more than anything, think big. With help from their record company, they started recording an ambitious, fourteen-track album in Paris and the US. Half of the songs featured singers, including Ghostface Killah from the Wu-Tang Clan on the track “Thrillah.”
