If I were to compile a group of examples of early stereophony experiments, let's limit this to record-company recordings and 2-channel, what's missing from this list: -- Blumlein EMI -- Bell Labs/Stokowski -- German 2-channel magnetic tape experiments on the AES CD -- Bert Whyte Magnecorder experiments 1952-53 -- RCA Reiner/CSO 1954 -- Mercury late 1955 -- Decca Ansermet -- other mid-50's American and European stereo commercial firsts The main thing I want to know is, am I missing any other pre-tape 2-channel experiments? I think only EMI and Bell Labs experimented with 2-channel disk recording in the 30's, to the point of actually making recordings. Thanks in advance for any corrections/additions. -- Tom Fine
