Spring 1990 is a live album by the rock band the Grateful Dead. It contains six complete concerts, on 18 CDs—one concert from each venue of their spring 1990 tour. It was released on August 31, 2012. Spring 1990 was produced as a box set, with a limited edition of 9,000 individually numbered copies. The box includes a 60-page hardcover book of essays and photos, along with memorabilia such as reproductions of the tour program, ticket stubs, and backstage passes. Speaking of the album in a 2012 interview with Rolling Stone, Bob Weir said, "For my money, this was our hottest era. We couldn't wait to go on tour; we couldn't wait to play because it was really working for us and it was keeping us amused. We had been working together as a unit for a good length of time.... We got comfortable enough in those tunes so that we could do a little exploration, harmonically, rhythmically, whatever. We could go places with them. Everybody has to be way in tune with each other to be able to do that." Looking back, Bill Kreutzmann said about the tour, "Brent played the best organ I’ve ever heard anybody play. He had the piss and the vinegar in him and he brought it to the table every night.
