The National Academy of Recording Arts and Sciences unveiled another batch of artists scheduled to perform at the Grammys on Sunday, including the first performance of the surviving members of the Beach Boys in 20 years.  The 60s heartthrobs had previously announced the reunion, originally scheduled to kick off April 27th at the New Orleans Jazz & Heritage festival, but the band will reportedly perform Sunday in a joint performance with Maroon 5 and Foster the People.
