I worked at Audio Assoc. and AudioKrafters in the late 70s, early 80s. We used a lot of Telarc discs, Sheffields, Nautilus, and even a Yamaha demo disc. The Yamaha disc was surprisingly good.
Some "popular" music we used was Dan Fogelberg and Tim Weisberg's "Twin Sons of Different Mothers", Steely Dan's "Aja" and "Countdown to Ecstasy", MFSL's "DSOTM", Virgil Fox organ discs, "Jazz At The Pawnshop" (yawn!), and MFSL's Al Stewart "Year Of The Cat". Also Poco's "Legend" sounded very good...
