Popular jam band O.A.R. is set to play The Lawn on July 12. The group is a popular live fixture with college students, particularly because the band’s beginnings coincided with rise of file sharing on campus computer networks. The band released its seventh studio album, King, last August. Most recently, O.A.R released a new single titled “Champions” in support of Team U.S.A. in the 2012 Summer Olympics. The band collaborated with rapper B.o.B. on the track. Opening for O.A.R. is reggae band Rebelution. The band released its third studio album, Peace Of Mind, in January of this year. The album debuted at #13 on the Billboard top 200 chart.
