In 1991 Sweet Exorcist (aka Richard H. Kirk of Cabaret Voltaire and Richard Barrett of Dark Matter, Vanity for BBC Orchestra) released CCEP/CCCD, marking Warp Records' first artist album release, one that would influence two decades of dance music. The new compilation, RetroActivity, is a double CD including Testone, Clonk and the aforementioned CCEP/CCCD. The 23 track compilation also includes five additional bonus tracks which are previously unreleased mixes and early versions.
