Leftism spans most of Paul Daley and Neil Barnes' singles output from 1992 to 1995 (excepting only "Not Forgotten") and adds several new tracks. Far from being just a stale progressive house LP, it spans a wide range of influences (tribal, dub, trance) and includes a good mixture of vocal tracks (with Toni Halliday, John Lydon, and Earl Sixteen) and instrumental workouts. [Leftism is also available in a release with added bonus tracks.] ~ John Bush, All Music Guide
