"Embryonic Journey" is an instrumental piece composed by Jorma Kaukonen, which originally appeared as the ninth track on Jefferson Airplane's second album Surrealistic Pillow.
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.
[3] Ultimate Classic Rock critic Michael Gallucci rated it Jefferson Airplane's 6th best song, saying that "It's a beautiful performance and a calming tonic to the rest of the album's druggy cacophony.
It was also included on the A Walk on the Moon movie soundtrack and in Ken Burns's documentary series The Vietnam War.
[5] Philadelphia disc jockey Ed Sciaky used it as a theme song for his long-running "Sunday Night Alternative" radio show.
