Just how decent is Mad Decent? Depends on how much you like to party, I suppose. Does a festival headlined by Major Lazer sound mad decent? What if it features Deli fave PO PO, dependably fun Georgian rock band Reptar, and tons of DJs? What if it promises to be one of the most fun events coming through Philly this summer? Is that decent enough to be mad decent? Yes, it’s that time of year again, the time where the Diplo-helmed Mad Decent Block Party hits Philly at Great Plaza at Penn’s Landing. Now in its fifth year, the party has extended to Toronto, New York, Chicago, and LA, and hits its hometown tomorrow for a free, all ages, nine-hours-of-dance-your-ass-off-music event. Were I in charge, I’d call it the Fuckin’ Awesome Block Party, but then again I suppose that’s why I’m not in charge of these things… Get there. Great Plaza at Penn’s Landing, Chestnut St. and Columbus Ave., 12pm – 9pm, Free, All Ages – Adam Downer
