The Grateful Dead hail from Palo Alto, and last summer they celebrated their 50th year with two concerts at Levi’s Stadium. They first played a concert at a party thrown by Ken Kesey and the Merry Pranksters at Fifth and Santa Clara streets in San Jose, where the City Hall dome now sits. Just up the street, Neal Cassady, Jack Kerouac and Allen Ginsberg made literary history. Those are just two footnotes in the rich history of an area that was central to the cultural and technological transformation of popular culture in the last third of the 20th Century. Bands like Moby Grape and Journey have their roots in the South Bay and on the Peninsula. The Doobie Brothers lived in a house on 12th Street in Naglee Park, next to Stevie Nicks and Lindsey Buckingham.
