Recorded and mixed at Duke Reid's storied Treasure Isle studio by Duke's nephew, young engineer Errol Brown, Dub Expression collects dubbed up treatments of seminal rockers rhythms crafted for Marcia Griffiths, John Holt, Dennis Brown and more. Propelled by the drums of Lowell "Sly" Dunbar, the appropriately named Revolutionaries (with their tough and radical sound) were the ideal group to reflect a turbulent period in Jamaican politics. While the band's personnel remained fluid – depending on which players were available and frequently overlapping with other seminal sessions bands such as Joe Gibbs' The Professionals and Bunny "Striker" Lee's The Aggrovators – The Revolutionaries were most known as Channel One's house band in the mid to late '70s.

The decision to top-bill The Revolutionaries, rather than feature an individual artist as was customary at the time, was made by Kingston's most celebrated female producer, Sonia Pottinger who shrewdly determined that The Revolutionaries' name alone would be a can't miss selling point. One only needs to spend a minute with Dub Expression to hear why. Originally released in 1978 on Pottinger's High Note label, Dub Expression represents the essence of dub in its purest form. An absolute classic. Liner notes by JR Gonne.
