Joel Selvin on 'Rock's Darkest Day'

The Altamont Free Concert, held 50 miles outside of San Francisco in 1969, featured the Rolling Stones, Santana and Jefferson Airplane and was billed as a “West Coast Woodstock.” But when the event turned violent and resulted in the death of four people, it “bookmarked the end of the 1960s,” according to rock critic Joel Selvin. He joins us in-studio to talk about his new book “Altamont: The Rolling Stones, the Hells Angels, and the Inside Story of Rock’s Darkest Day.”
