Details: Deluxe two CD 50th Anniversary edition. This double disc set includes two versions of the original album - one fully remastered from the original 1968 mix, and the other remastered from the more well-known 1971 mix. Both mixes of the albums were mastered by Grammy-winning engineer David Glasser from the original analog master tapes. The set also includes a bonus disc with a previously unreleased complete live show recorded on October 22, 1967 at Winterland in San Francisco, CA. The band's most experimental album, Anthem Of The Sun was an unprecedented mix of studio and live recordings stitched together to create a hybrid. Fifty years later, it remains a pinnacle of psychedelic music. It also marked a departure for the band, as they began to channel their creativity into longer jams on songs like "Alligator" and "Caution (Do Not Stop On Tracks)" - two live staples of the Dead's early days. "This is one the most thrilling albums The Grateful Dead ever produced, mixing portions of live recordings from the first six months of Mickey's tenure with the band, along with studio experimentations that would hint at where the Dead would go when they started recording to 16-track tape the following year."
