March 12: Jay-Z doing what he does best, on the mic at the Moody Theater.

Before he toasts his hometown's new basketball team with a concert at the new Brooklyn Nets arena in September, Jay-Z will take a trip down the turnpike on Labor Day weekend to headline and curate his own two-day festival in Philadelphia, with proceeds benefiting the United Way.

The rapper will star in the Budweiser Made in America music festival, which will invade Philadelphia's Fairmount Park on Sept. 1 and 2. Jay-Z and Philadelphia mayor Michael Nutter are expected to officially announce the festival at a press conference on Monday morning.

"This Labor Day, we will not only make history but we're benefiting a great organization," says Jay-Z in a statement. "'Budweiser Made in America' will encompass every genre of music, creating and showcasing the only genre that matters, 'great music.' Budweiser and Live Nation are going to produce an amazing two days of performances, and it's great to partner with United Way again to support all of the positive work they do in the community."

The festival is being produced by Live Nation, with tickets going on sale on May 23. No other performers have been revealed yet, although a press release promises "acts ranging from rock, hip-hop, R&B, Latin and dance."

Later in September -- Sept. 28, to be exact -- Jay-Z will perform at the Barclays Arena in Brooklyn to celebrate the borough's new basketball franchise, which he partially owns. Last month, the Brooklyn Nets revealed their new team logo, which was personally designed by the rapper.

The Budweiser Made in America festival would offer a nice book-end to Philadelphia's hip-hop-centric summer festivals, with the Roots Picnic fest taking place on the first weekend of June for the fifth straight year on June 2-3.
