Other versions of "Embryonic Journey" were recorded by Kaukonen and featured on an album sharing the song's name. According to that album's liner notes, Kaukonen composed the tune in 1963 as part of a guitar workshop in Santa Clara, and included it on Surrealistic Pillow at the band's behest.[2] According to Kaukonen, the song "evolved from... messing around on a 12 string in drop D".[3]
