    perform at the Bonnaroo Music and Arts Festival, in Manchester, Tenn. Fifty years at Woodstock, the
    mystical and messy event that became the father of all musical festivals, the entertainment industry is
    diluted with festivals and events like it, some genre specific, some extremely diverse and others
    offering experiences in addition to music, ranging from food to art, in order to appeal to wider
    audiences. (AP Photo/Mark Humphrey)
