Mark’s music runs from instrumental guitar (Rubato, Equinox) to matched vocals with Cindy Lemaire (Cambridge Cowgirl, Home Isn’t Home) — the harmonies so aligned that they often seem like two people with one voice. As a recording engineer, his clients have ranged from Jimmy Miller (Rolling Stones, etc) to the San Francisco Symphony. Mark's musical well is deep. The work is nuanced, real, and unlike anything else you’ll find.
