Details: Debut studio album by the American Latin rock band. Over half of the album's length is composed of instrumental music, recorded by what was originally a purely free-form jam band. At the suggestion of manager Bill Graham, the band took to writing more conventional songs for more impact, but managed to retain the essence of improvisation in the music.
