Jay-Z, Young Jeezy, Mary J. Blige Shut It Down At Summer Jam 2009

EAST RUTHERFORD, N.J. (WPIX) - Forget about Barnum & Bailey, the greatest show on earth went down in East Rutherford, N.J. over the weekend.

New York radio station WQHT Hot 97 brought together the biggest acts of hip hop and R&B to one stage at Giants Stadium Sunday for Summer Jam 2009.

Thousands of fans crammed into the venue for a nearly sold-out show that boasted a historic lineup that matched up music veterans with up-and-coming rookies.

"I've been to a couple of Summer Jams, but this is so far the best!" chimed concert goer Jacqueline Cruz, who snagged a front row seat to the colossal event.
