On this day in music history: May 11, 1970 - “Woodstock: Music From The Original Soundtrack And More” is released. Produced by Eric Blackstead, it is recorded at Max Yasgur’s Farm in Bethel, NY from August 15 - 18, 1969. The twenty one track three LP set serves as the soundtrack to historic three day concert and Oscar winning documentary film in which over a half a million people attend. Recorded by engineer Eddie Kramer (Jimi Hendrix, Led Zeppelin, KISS), the album features performances from Richie Havens, Canned Heat, The Jefferson Airplane, Crosby, Stills Nash & Young, Santana, Joe Cocker, Joan Baez, Country Joe & The Fish, The Who, The Butterfield Blues Band, Sly & The Family Stone, John Sebastian, Arlo Guthrie, and Jimi Hendrix. The soundtrack is a huge success and spins off a sequel album the following year featuring more performances from the festival. To commemorate the 25th anniversary of the festival in 1994, Atlantic reissues the albums as a four CD box set including previously released performances. A further expanded six CD box set issued in 2009 for Woodstock’s 40th anniversary that include more unreleased material. “Woodstock” spends four weeks at number one on the Billboard Top 200, and is certified 2x Platinum in the US by the RIAA.
