For an international audience reawakening to the influence of Chicago house during the 1990s, Curtis A. Jones acted as quite a renaissance leader. Besides donning his straightahead house guise Cajmere and a flamboyant, neon-haired acid-house alter-ego named Green Velvet for several of the most memorable underground house tracks of the decade (including "Preacher Man," "Answering Machine" "Brighter Days" and "Flash"), Jones helmed the two most respected labels in the new school of Chicago house, Cajual and Relief.
