ArtsBeat is reporting that a two-day music festival curated and headlined by Jay-Z will be officially announced Monday morning. The scoop: “As many as 28 musical acts†from a number of genres at Philadelphia’s Fairmount Park on September 1 and 2. Tickets for this beast go on sale May 23; start speculating what a lineup hand-picked by Jay-Z looks like. (Do not, however, suggest any cool fest monikers — it’s the Budweiser Made in America Music Festival. Moving on.) UPDATE: You can watch video of the announcement here.
