The Grateful Dead will release one previously unreleased show recording from each year of the band’s history. The 80-disc box set, which has been dubbed Thirty Trips Around The Sun: The Definitive Live Story, will be available on September 18 via Rhino Records.

The incredible box set will feature 73 hours of music, with one show from each year that the band was together from 1966 to 1995 and one track from their earliest recording sessions in 1965. Among those are recordings of the band’s November 10, 1967 concert at the Shrine Auditorium in Los Angeles, their October 27 1979 show at the Cape Cod Coliseum in South Yarmouth, MA, their September 18, 1987 performance at Madison Square Garden and their October 1, 1994 show at Boston Garden.

Rolling Stone reports that Grateful Dead archivist David Lemieux first had the idea for Thirty Trips Around The Sun in 2012, when he told members of the Rhino staff that the label needed to “go big in 2015.” A post from Lemieux on dead.net reads:

When we began discussing audio projects to commemorate the 50th anniversary of the Grateful Dead back in 2012, we knew we wanted to do something completely unprecedented. We could think of nothing more exciting or ambitious than a career-spanning overview of the band’s live legacy focused on what best tells the story: complete concerts. Our first criterion was the very best live music to represent any given year in the band’s history. We wanted to make sure that there were not only the tent-pole shows that fans have been demanding for decades but also ones that are slightly more under the radar, but equally excellent. For those who listen to the entire box straight through, chronologically, the narrative of the Grateful Dead’s live legacy will be seen as second to none in the pantheon of music history.

Fans will have the option of purchasing Thirty Trips Around The Sun in its 80-disc format, or as custom lightning-bolt USB drive. The box set will go for a retail price of $699.98. More information can be found here, and a sneak peak of the “Morning Dew” from 9/18/87 can be heard via Rolling Stone.
