Mark has over 20 years experience as a recording engineer and music producer, working on major and minor label album projects as well as television commercials, promos, short films, sales videos, audiobooks and corporate training videos. He has been credited on dozens of albums by artists as varied as Peter Gabriel, Sting, Phoebe Snow, and Roger Daltrey, among others. Mark received a Grammy nomination in 1992.

From 1993 to 1999 Mark ran the in-house recording studio at McCann-Erickson in New York, one of the world's largest advertising agencies. While there he worked on literally hundreds of television and radio commercials.

In 1997 he founded Zampella Music, a royalty free production music library. In the past 12 years, the company has grown from production music alone to now include film scoring and studio design and consultation as well. Environments is a line of environmental recordings captured in various locales.

In 1999 Mark designed and supervised the construction of UltraSound, an audio post production room in NYC. He operated the room for three years, building up a large agency clientele.

Mark started a freelance career in 2002, continuing his work as an audio engineer, as well as incorporating graphic, web design, and video projects into his busy schedule. Mark has been a guitarist and vocalist for the past 25 years in numerous cover and original acts. He currently plays at Sarasota-area bars and cafés as a solo artist, as well as with his band, Another Roadside Attraction. For his current schedule, check the home page.

Since 2007 Mark has hosted Complex Waveforms, a weekly 2-hour radio show which airs every Friday from 1-3pm on WSLR, Sarasota's local community radio station. The main focus of the show is the creatively-fertile area where world, ambient, and electronica meet. Contemporary North African and Middle-Eastern music is featured prominently, alongside artists such as Robert Fripp, Bjork, and Brian Eno. WSLR is a 100-watt station, referred to as low power FM, with an understandably limited range. You can, however, take advantage of the magic of the internet and listen in via streaming from the station website at wslr.org. The Herald Tribune ran a nice piece on Mark and Complex Waveforms in their "Local Beats" section...check it out.
