Oxygiene 23 were an American trance collective that emerged from Chicago with a distinctive blend of atmospheric electronic music and live instrumentation. The group—anchored by keyboardist Van Christie, vocalist Jane Jensen, and percussionist Jim Marcus—crafted introspective trance compositions that drew inspiration from mythological themes and new-age soundscapes, setting them apart from the more club-oriented trance acts of their era.
The group's sole studio album, *Blue* (1995), released on Fifth Colvmn Records, showcased their signature approach to trance music: layered synth textures combined with organic instrumentation and ethereal vocal performances. Though short-lived, Oxygiene 23 contributed to the late-90s underground trance scene with a more experimental, introspective aesthetic that prioritized atmospheric depth over dancefloor immediacy.
