As part of the band’s ongoing 50th anniversary series, the Grateful Dead will release a two-CD deluxe edition and a special picture disc vinyl edition of Anthem of the Sun on July 13.

The album combines studio cuts and live recordings of early Dead favorites like “Alligator,” and the two-disc package (mastered by Grammy winner David Glasser) includes two versions of Anthem, one “from the original 1968 mix,” and the other from the “more well-known 1971 mix.” The vinyl version (limited to just 10,000 copies) will just include the 1971 mix.

The Anthem of the Sun 50th anniversary double CD edition also includes a previously unreleased live cut of a October 22, 1967 show at the Winterland in San Francisco. Interestingly this 10/22/67 show is the first known appearance of percussionist Mickey Hart, who joined the band just one month prior.

“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,” Grateful Dead archivist and producer David Lemieux said in a statement. “The 1971 remix, produced in order to make the album more accessible to the newer fans who were brought on board with Workingman’s Dead and American Beauty, has been the most commonly heard version for the past 45+ years. However, having this side-by-side with the original 1968 mix demonstrates countless differences, with the original mix being more primal, psychedelic, and experimental.”
