this is the only bit of a bio i could find of them on the web. They are probably priests now or floating between rooms in the vaults of Tresor.

The Holy Ghost was one of the more theatrical techno producers of the late '90s, recording two full-length albums for Tresor: The Mind Control of Candy Jones (1996) and The Art Lukm Suite (1997), both considerably conceptual. In addition to the albums, Tresor also released a few Holy Ghost 12"s, which became quite popular among the global techno audience. In addition to appearing on several CD mix-albums and compilations, the Holy Ghost toured as a live act. In fact, the act's live show often overshadowed its recordings. By the end of the '90s, the Holy Ghost's relationship with Tresor had come to a halt, along with its recording output. ~ Jason Birchmeier, All Music Guide
