Here are two links to sites that give some history of Radio Recorders; http://www.scottymoore.net/studio_radiorecorders.html http://www.smecc.org/radio_recorders_-_santa_monica_ca_.htm Sadly both sites focus on the R&B and pop hits that were recorded there and make no mention of the role that Radio Recorders played in recording jazz in the 1940s and 1950s.
