Born 3 April 1949, Yonkers, New York, USA.
Senior mastering engineer who began his mastering work in 1973 at Masterdisk for 4 years, before eventually returning to Sterling Sound again in 1998. Etched GC or gc, ☆, or ⚾ (a baseball - can be mistaken as H or M in circle) can often be found near the Sterling stamp in a runout. Do not create Alias or ANVs for the symbols, they can be added in the credit section as "Lacquer Cut By [Runout Etching ☆ or ⚾] - Greg Calbi".
