Jay-Z will join Mayor Nutter atop the Art Museum steps at 10:30 Monday to announce a multi-day concert festival called Made in America over Labor Day weekend.

It is unclear whether the event will be held on the Parkway or elsewhere.

Jay-Z posted this video featuring the Philadelphia skyline, screaming fans and a microphone, on his website Friday.

Made in America was the name of a track from Jay-Z and Kanye West's album "Watch the Throne."

The New York Times reported Sunday night that the Budweiser Made in America festival runs Sept. 1 and Sept. 2 in Fairmount Park and that tickets go on sale May 23 through LiveNation.com and Ticketmaster.com.
A portion of proceeds are to benefit the United Way of Greater Philadelphia and Southern New Jersey.
