Due to the relentless touring of the Grateful Dead, and the fact that fans were allowed to tape the band's shows, many live versions of "Dark Star" exist. The studio recording of "Dark Star" lasted only 2:40, yet the song was known for its lengthy live performances, many of which clocked in at 20–30 minutes. Running over 23 minutes (13 minutes of it consisting of Jerry Garcia's guitar solo), the popular rendition as found on the "Live/Dead" live album was a blend of psychedelia, jazz, and jam elements. "Dark Star" defines the Dead's early improvisational music.
