For anyone with an interest in the history of house music, this excellent compilation from Jerome Derradji's Still Music imprint should be essential listening. It focuses on the output of two long forgotten Chicago labels, Mitchbal and Chicago Connection Records, during the early to mid 1980s, when electro, new wave and boogie were morphing into house. As such, 122 BPM offers a mix of rare, largely overlooked cuts that bristle with analogue dancefloor intent. There's proto-jack in the shape of Jeanette Thomas's "Shake Your Body" and Z Factor's "I Am The DJ", dubbed-out Chi-town proto house from Mitchbal and Larry Williams, and some terrific bodypoppin' electro from McGhee.
