Explosion of Deferred Dreams [PDF ebook] 

As the 50th anniversary of the Summer of Love floods the media with debates and celebrations of music, political movements, ‘flower power’, ‘acid rock’ and ‘hippies’; The Explosion of Deferred Dreams offers a critical re-examination of the interwoven political and musical happenings in San Francisco in the ’60s. Author, musician and native San Franciscan Mat Callahan explores the dynamic links between the Black Panthers and Sly and the Family Stone, the United Farm Workers and Santana, the Indian Occupation of Alcatraz and the San Francisco Mime Troupe, and the New Left and the counterculture.
