Two CD’s featuring the Human Expression and also solo recordings by Jim Quarles have been released by Cicadelic Records, Love at Psychedelic Velocity (1994) and The Human Expression & Other Psychedelic Groups (2000).  The first CD is named after their best known song, “Love at Psychedelic Velocity” (actually more of a garage rock song that has remarkable changes in tempo), which is included on the Pebbles, Volume 10 LP and also the first Nuggets Box Set.  “Optical Sound” – whose title likely refers to synesthesia, when the human senses are sometimes scrambled during an LSD trip – actually appears on more than twice as many compilation albums.
