Really, I started on this when the sun was shining, I looked up when I finished both parts, the sun was down, my kids and wife had gone to Chili's and I didn't even hear them leave. Bob has uncovered so much new, good information it's beyond belief. (for example, Capitol did stereo test recordings in 1952? I knew Atlantic did, but Capitol?) (Wait, WDRC AM did stereo radio in 1924????) (First stereo movie: Universal's "100 Men And A Girl" recorded in multi-channel in 1937???) It's also crazy that I've actually remastered many of these early stereo gems, sometimes without realizing how pioneering they really were, or exactly how old. Take it from me, check this out. It starts way back and ends with the first year of stereo records. Fascinating. http://www.3dfilmarchive.com/binaural-or-bust http://www.3dfilmarchive.com/first-year-of-stereo-records I'm putting this as a sticky. If you collect records, if you love records, if you love music, if you love the history of recorded sound, this is for you!
