The Grateful Dead will celebrate the 50th anniversary of 1970’s Workingman’s Dead with a deluxe reissue of the acclaimed Americana rock album.

Announced on Wednesday, Workingman’s Dead: 50th Anniversary Deluxe Edition will arrive via Rhino this summer on July 10th, and will include a mix of unreleased and archived material from what many Deadheads believe is the band’s strongest creative era as the band charged into the 1970s with a drastic change in their psychedelic sound. The deluxe reissue will be released as a three-CD set, vinyl picture disco (10,000 copies), and colored vinyl (2,000 copies).

In addition to the original eight tracks with newly remastered sound, the reissue will also come with the soundboard concert audio from the Dead’s February 21st, 1971 performance at the Capitol Theatre in Port Chester, NY. The concert audio was mixed from the show’s 16-track analog master tapes by Jeffrey Norman at Bob Weir’s TRI Studios, and re-mastered David Glasser.

Listen to the recording of “Casey Jones” from the February 1971 performance below.
