day music festival that celebrated peace and love during a time of protest and anger at the Vietnam War, Woodstock nostalgia is in full commercial flow. - Survivors from some of the acts that played Aug. 15-17, 1969 will again take the stage on what was Yasgur's Farm, but is now the Bethel Woods Center for the Arts in upstate New York. The “Heroes of Woodstock” show on Aug. 15 features the Levon Helm Band, Jefferson Starship, Ten Years After, Canned Heat, Big Brother and the Holding Company and Country Joe McDonald. - Meanwhile the movie “Woodstock” has been re-released in a 40th anniversary director's cut, along with the 2-CD soundtrack, while Rhino Records has put out a 6-disc box set featuring every performance at Woodstock. - Later this month, director Ang Lee will debut “Taking Woodstock,” a movie about a man working at his parents' motel who inadvertently sets in motion the concert. - For many, the definitive story of that Summer of Love is “The Road to Woodstock,” a book by Michael Lang, one of the organizers of the festival.
