Bonnaroo 2008: Pearl Jam, Metallica, My Morning Jacket, M.I.A. and More Rock America's Best Fest

Pearl Jam used their Saturday night Bonnaroo '08 closing set to unleash some rarities on June 14, 2008. The band kicked off with "Hard to Imagine," a gorgeous ballad they've only played a few dozen times since 1992. Later, they covered the Who's "Love Reign O'er Me" and Bob Dylan's "All Along the Watchtower."
