Dolph worked in the studio with colleagues Kenny Ascher and Alan Foust; they billed themselves as the Moog Machine for this and one more project.

In 1967 he paid for the recording session of the album The Velvet Underground & Nico, and he helped engineer it.

[3][4][5] The idea for Switched-On Rock was conceived by Columbia Records marketing executive Russell "Russ" Barnard.

Barnard assigned the project to three men: Dolph supervised the album and he tuned the Moog modular synthesizer, and his associates jazz pianist Kenneth "Kenny" Ascher and arranger Alan Foust played the keyboards and wrote the song arrangements, respectively.

They also coined "pagwipe" (a leaky bagpipe), "jivehive" (many bees swarming on the same pitch) and the "sweetswoop" (the roaring of a jet with harmonics).

"[8] However, in its September 1970 issue, Stereo Review magazine gave it a "Recording of Special Merit" designation.

Reviewer Peter Reilly said, "this is one of the most entertaining albums of the year" and "The recorded sound is truly superb and the engineering immaculate.

"[7] After Switched-On Rock was released, Dolph, Ascher and Foust quickly regrouped as the Moog Machine to create one more album, this time featuring Christmas songs.
