The two-LP set contains more material from many acts featured on the first Woodstock album with additional performances from Mountain and Melanie.

[2] The tracks by Mountain were in fact not from their Woodstock performance but rather a show recorded at New York's Fillmore East.

Woodstock Two was originally released in 1971 as a double LP set[2] The first CD release was released by Mobile Fidelity Sound Labs (as a 4 CD collection with the original Woodstock triple LP) and was re-released as a double CD by Atlantic in 1988 and re-issued in 1994.

Also in 1994 the songs from both albums, as well as numerous additional, previously unreleased performances from the festival, but not the stage announcements and crowd noises, were reissued on a 4-CD box set titled Woodstock: Three Days of Peace and Music.

An even more comprehensive 6-CD set, Woodstock: 40 Years On: Back to Yasgur's Farm, was issued by Rhino Records in 2009.
