After disbanding his first guitar outfit, Line Up, 'Oh began as a DJ in 1990 and worked his way up to production with the 1993 limited release of "Randy -- Never Stop That Feeling," a cheery, helium-sampled single that found its way to the top of Germany's charts for half a year after its re-release. Subsequent singles furthered 'Oh's light Super Mario Brothers trance style and his three albums -- 1995's Never Stop That Feeling, 1996's Magic Power, and 1999's Rebirth -- showed an increase in guest appearances and unusual covers, such as reworkings of Visage's "Fade to Grey" and Nick Kamen's "I Promised Myself." A premature Best Of collection was released in 2001.
