Though it's not as well known, 1967's Monterey Pop Festival is often seen as a precursor to Woodstock and a key moment in the Summer of Love. Its success helped demonstrate both the breadth and the depth of the hippie movement. Held from June 16 to 18 at the Monterey County fairgrounds in California, the event attracted over 200,000 people and featured a disparate range of musicians, including Ravi Shankar, the Who, Otis Redding and Jimi Hendrix. The Jefferson Airplane were there too, and today's version of the band's classic "Somebody to Love" comes from a new double-disc compilation of live Monterey performances. It may be 40 years old, but "Somebody to Love" still rocks -- hard.
