Not absolutely true: Perfekte Stereo-Demonstration. "Pop's". Hollywood. Motion in percussion. Supposedly recent stereo recordings.
True: There are only a few stereo-effects added later. Robert Lowden leader of huge Orchestra. 4 fine Lowden and Kuhn compositions. Too many strings dominate the percussion effects. Recorded in 1960 already (possibly in Mono). It was an easy deal by D.L. Miller again.
Also true: Today this one is regarded as a "Spaceage-pop-jazz" cult album and NOT as a Stereo-Demonstration LP.
