A massive 38-disc Woodstock boxset is coming out this summer

Over 400,000 people attended Woodstock in 1969, to see performances from Jimi Hendrix, The Who, Crosby, Janis Joplin, Grateful Dead, and many others.

The comprehensive box set spans 432 tracks, and also features nearly 20 hours of previously unreleased material. All the tracks are arranged in chronological order, right down to the date and time.

The 36 hour box set will also include a Blu-Ray copy of the Woodstock film, two posters, a guitar strap, a diary from an anonymous attendee, prints, essays, and a book about the event written by one of the festival's co-creators, Michael Lang.

Andy Zax, the producer and archivist who co-produced the set, said to Rolling Stone, "The Woodstock tapes give us a singular opportunity for a kind of sonic time travel, and my intention is to transport people back to 1969. There aren’t many other concerts you could make this argument about."
