Sad news...John Matousek passed away on May 27th. He was a long time Motown mastering engineer and was responsible for mastering a large chunk of Motown's catalogue starting in the mid 70's, up until the early 90's...including many of the anthologies and Compact Command CD series that we've all purchased, enjoyed and loved. The first link below is his obituary and the second link is a listing of the various releases he worked on, from Discogs' database. Thank you for working your magic, John. Rest in peace.
