Frank Peterson is a German music producer.
As a child he taught himself how to play the piano and keyboard, going on to work in a music store. It was here that he met Michael Cretu and became lead keyboardist for Sandra, appearing prominently on her hit single Maria Magdalena.
He was a member of Sandra's band for a few more years, moving with the Cretus to Ibiza after a few years. It was here that he became involved with Cretu's new project, Enigma, under the pseudonym of F. Gregorian.
Peterson left the group in 1991 and pursued work on Gregorian, a musical project co-founded by Thomas Schwarz and Matthias Meissner.
Today, he is most known for being the producer and one-time boyfriend of Sarah Brightman, collaborating with her on most of her solo albums since Dive.
Other artists whom Peterson has worked with include Princessa, Violet, and Sinsual (the last two of which have CDs in the works).
