 Initial recordings took place in Chicago in September 1966, but these were not satisfactory, and the band returned to San Francisco.The band recorded the tracks "Blindman" and "All Is Loneliness" in Los Angeles, and these were released by Mainstream as a single, which did not sell well.After playing at a "happening" at Stanford in early December 1966, the band traveled to Los Angeles to record 10 tracks between 12 and 14 December 1966, produced by Bob Shad.
