Written by Paul Kantner, the song initially appeared as an RCA Victor single, and then subsequently as the first track of their third album, After Bathing at Baxter's, in a substantially remixed version.

[2] Cash Box said that "insistent throbbing rhythm, guitar showers that change hues almost in a 'color show' style, psychedelic sound effects and the singular vocals of the Jefferson Airplane create a love-in, happening and carnival all rolled into one.

"[3] Record World called it an "excursion into the mind and the electronic control board and other current pop Jefferson Airplane places.

[5] Ultimate Classic Rock critic Michael Gallucci rated it Jefferson Airplane's 9th best song, calling it "a glorious mess of guitars, drums and vocal sparring between [Marty] Balin and [Grace] Slick.

"[6] Live versions of the song typically began with an extended feedback segment by guitarist Jorma Kaukonen and included a bass guitar solo by Jack Casady after the second verse, often lasting several minutes.
