Documentary celebrating the male artists whose vocal stylings have played an instrumental role in the soul genre from the 60s to the 00s. Featuring footage of Brenton Wood performing Gimme Little Sign and Curtis Mayfield singing Keep On Keeping On, as well as appearances by Billy Preston, Bill Withers, Billy Ocean, Alexander O'Neal, Bobby Womack and Barry White. They’re mainly performances from Top of the Pops, The Old Grey Whistle Test and Jools Holland, so Al Green rubs shoulders with R Kelly, Luther Vandross, Bill Withers and the Commodores. It’s perfect late-night viewing. Boogie the evening away or just slump on the sofa, close your eyes and, as Dobie Gray says, drift away.
