Sons Of Slum released three singles on Stax and Gamma in the 1970s. They were reputed to be Chicago's finest live band of their time, the band broke up in 1978. 'Music Is Message' is a high octane funk and soul crossover jam which which has the potential to be a future classic. On the flip the tempo is lowered and a rasping horn supplements the killer groove with a smoothing vocal delivery. Cordial Recordings will release an album of previously unreleased songs that were recorded back in the mid 1970s in 2019.
