The concert was held in response to Hurricane Sandy, which devastated portions of Northeastern United States, the Caribbean and the Mid-Atlantic in late October 2012 and cost an estimated $63 billion in damage in the United States. The concert was broadcast live via television, radio, movie theaters and the Internet across six continents. Proceeds from the event were collected by the Robin Hood Relief Fund to benefit victims of the hurricane in New York, New Jersey and Connecticut.
Many famous performers took part in the charity event, including Bruce Springsteen, Alicia Keys, Bon Jovi, Eric Clapton, Billy Joel, The Rolling Stones, Roger Waters, Chris Martin, Michael Stipe, The Who, Kanye West, Eddie Vedder, and, for the first time in eighteen years, the surviving members of Nirvana (Dave Grohl, Krist Novoselic and Pat Smear) who performed together in a collaboration with Paul McCartney during his show-closing set. -Wikipedia
