Petersen scored most of season 4 of Miami Vice in 1987/88, in addition to the 1984 Voltron series, the feature film Childless, and a few other series. He also scored the 1995 film The Keeper.
The composer seems to have released the 12 track (28 minutes) disc on his own label, Alchemy, in 1998. The music is quite interesting, musically not a mile away from the stuff he did for Miami Vice. Quite brooding and atmospheric, with nice guitar work and enjoyable sax by Stan Harrison. It's a pity that he never really entered the film music business in a proper way.
