After leaving San Francisco's Galileo High School in the summer of 1962, Pat Kilroy enrolled at the University of California at Berkeley where he would later meet Susan Graubard.
Kilroy and Graubard then traveled to Europe and Morocco, before returning to New York to complete the album[4] with additional musicians including guitarists Stefan Grossman and Marc Silber, and Eric Kaz on harmonica.
The album, Light of Day, released in October 1966, contained material all composed by Pat Kilroy using a wide range of instrumentation including jaw harp and congas, as well as improvised vocals.
Although the album was not commercially successful, it has subsequently been suggested as an influence on similar music recorded later by The Incredible String Band (who Kilroy and Graubard had met whilst staying with their producer Joe Boyd in London), Sandy Bull and Tim Buckley.
Kilroy, Graubard and Stewart had all learned to play eastern instruments and in the late summer and early fall of 1967 they entered Warner Brothers Studios in Los Angeles and recorded a number of "improvised psychedelic acoustic" tracks which went unissued for several decades.
