It's been about a year since episodes 1 and 2 of the RPM Chronicles so this week we're returning to the topic of mastering for vinyl. You cannot talk about mastering for vinyl without lathes, and you cannot talk about lathes without mentioning Al Grundy.

Al Grundy has been working in pro audio for over 50 years, and after buying a glut of Neumann lathes form Sterling Sound in the 90s, he became a go-to guy for scoring a complete disc cutting system.

Al spoke with me about his amazing career, the differences between Scully/Westrex and Neumann cutting systems, and how preparing masters for vinyl has changed through the years.

Music: Buju Banton "Untold Stories"
