The top Google result for dead is not a dictionary definition of the inevitable human condition. Rather, it is the official site of legendary psychedelic band the Grateful Dead, whose tie-dye-loving fans have channeled the Haight-Ashbury vibe for decades. Deadheads made a point of following the group led for 30 years by singer Jerry Garcia on tour, attending concert after concert, which they were encouraged to record. These fans spanned several generations, persisting long after the end of the hippie era.
