By any measure, 1970 was a high-water mark for the Grateful Dead. Hot on the heels of the incredible success of Workingman’s Dead that summer, the band returned in the autumn with the equally stunning American Beauty. Those back-to-back classics not only introduced songs that would be a key part of the group’s live repertoire for decades, but they also opened a gateway into the world of the Grateful Dead for generations of Dead Heads. American Beauty celebrate its 50th anniversary this year with a new three-CD set, which includes the original album with newly remastered audio, plus an unreleased concert recorded on February 18, 1971 at the Capitol Theatre in Port Chester, NY. The show was mixed from the 16-track analog master tapes by Jeffrey Norman at Bob Weir’s Marin County TRI Studios and mastered by Grammy Award-winning engineer, David Glasser.
