Exchange consists of a pair of Canadian keyboardists, Gerald O'Brien and Steve Sexton, who create atmospheric music. O'Brien picked up experience playing rock and pop music and wrote the music for the soap opera Generations. Sexton has backed many pop singers including Dionne Warwick, Rita Coolidge, Dusty Springfield and especially Anne Murray. The duo met up while playing with the rock group Surrender, they kept in touch, and formed Exchange in 1986, a unit whose original name was So Ho, until it was discovered that another band had the same name. Exchange (strictly a recording group since their sound utilized extensive overdubbing) recorded two sets for Mesa during 1988-89 that fell into the "progressive instrumental" music genre that overlapped with New Age. ~ Scott Yanow, All Music Guide
