The idea of these demonstration records cut in conjunction with audio component makers was so incredibly cool! Several records in my collection including records by Dynaco also were made with contemporary artists giving them an opportunity to reach a wider audience (at least that was the hope) and really made the entire "hi-fi" experience a complete immersion in the sound and artistry of the times. The performances contained herein are excellent and of course the recording is flawless, with a complete rundown of equipment used and studio techniques included.
