GBHighly recommended Marc is a real pro. I've done several projects with him, touring and in the studio, and he has never failed to get the best results. We did a session recently during COVID, and he set up everything ahead of time with regard to safety precautions and protocols. We were very comfortable in the studio and able to perform without thinking about any of the technical matters. Highly recommended.

GBExcellent work! We recorded a New York Jazz Record (Hasbrook Heights- Manu Lafer), and the entire production was smooth, very professional and simply excellent! I recommend Marc’s Services to every musician, company or high end production of any sort as well as to independent producers,and to any artist with a project which you will want to see coming to fruition. Marc is a 5 Star multilingual recording/ Sound Engineer, and simply my first choice in the United States of America. Thank you for all Marc! Your work is outstanding! Musically, Annie Moore
