by Heather PharesVolume 2: Release, Afro Celt Sound System's eagerly anticipated second album, continues the group's dedication to hypnotic grooves and innovative arrangements. Ancient and electronic elements blend in a timeless, ethereal fashion, transcending world and dance genre labels. Sinead O'Connor provides vocals on the first track, and an interactive music game is included as a bonus track. Volume 2: Release is a complex, complete artistic statement from a unique, open-minded group.
