This Is Dynagroove

I found this LP the other day, extolling the many advantages of Dynagroove records. This was the revolutionary new recording process that followed Living Stereo and Stereo Action at RCA. Apparently, they couldn't come up with anything that was good enough to last more than a couple of years. And while the other processes are mythologized to this day in certain circles, Dynagroove was not welcomed in audiophile circles. This Is Dynagroove (RCA Victor PRS-140, 1963) features 11 cuts in total, 5 from the pop side of things, and 6 from the classical arena. Sid Ramin, Marty Gold, Dick Schory, Hugo & Luigi Chorus and Peter Nero are the pop names here. The classical side features two cuts from Arthur Fiedler & The Boston Pops, and Erich Leinsdorf, Charles Munch, Leontyne Price & Richard Tucker and Morton Gould each get a single track. The back of the record promises the technical story behind Dynagroove is inside, but my copy has no insert or inner sleeve. Time has robbed me of the true facts behind Dynagroove! By the way, that cover image is a photograph of an actual Dynagroove record taken through a microscope.
