Rock’s Ridiculously A-List Jam Session

The Rock and Roll Hall of Fame is usually known for commemorating history, but this time they may have created it. In celebration of the institution’s 25th anniversary, music legends from across the board were brought together for two nights at New York City's Madison Square Garden, in concerts that "succeeded in letting rock take an unpretentious look in the mirror," said the New York Post. During jam sessions that chronicled the history of rock, U2 played alongside Bruce Springsteen and Mick Jagger. Other performers included Lou Reed, Sting, Aretha Franklin, Metallica, and Crosby, Stills & Nash. For those unlucky fans who couldn’t afford tickets, an abridged version of the concert will air November 29 on HBO.
