Canadian mastering and cutting engineer who worked at:
- RCA Studios, Toronto from ca.1968 to 1976
- The Lacquer Channel Limited from 1976 to ca. 1977
- J.A.M.F. from ca. 1978 to ca. 1980
- Masterdisk from ca. 1980 to the mid '90s

His work for [l299013] and [l426483] can be identified by an etched GAM in the runout.
The marking is not to be confused with Masterfonics engineer Glenn Meadows who also used GAM but additionally always contained Masterfonics

His Masterdisk runout signature etching looks like AΛ, ΔΛΛ or a more continuous ⩟∧∧. It is always accompanied by a stamped MASTERDISK. In all these cases please credit as ANV AM.
The marking is not to be confused with same era Frankford/Wayne Recording Labs engineer Dave Moyssiadis or 60's UK engineers Derek Moore (3) and Malcolm Davies who used a similar ΔM etching or with engineers who etched 'AM' such as Alain Morand (France), AM (20) (Italy) and Andy Miles (2) (UK).
