Jefferson Airplane Volunteers

This four-disc box set was released commemorating the 25th anniversary of the original Woodstock festival that took place in August 1969, and combined both of the Woodstock albums released in 1970 and 1971 with previously unreleased material. It's a well-known part of the festival's history that many of the participants played self-confessed lackluster sets. However, considering the surrounding circumstances in which this music was conceived – not enough food or water, an abundance of drugs, and thunderstorms – these artists manage to rise above it more often than not. What is most interesting about this box set are the unreleased tracks by the Band, Tim Hardin, Johnny Winter, Creedence Clearwater Revival, Jefferson Airplane, Jimi Hendrix, Janis Joplin, and Ritchie Havens. A whittled down single-disc sampler featuring many of the aforementioned unreleased tracks are also available on Woodstock Diary containing Mountain's "Southbound Train," Sly and the Family Stone's "Love City," and CS&N's "Blackbird" which aren't included on the box set.
