This weekend is overloaded with big events, but I only have time to mention a few...
Friday night, the 4AM party is back to kick off the summer. DJ Dirty (from the Sundae party) and promoter turned dj Jay Yo are the men behind this event. Each month they bring guest performers and djs to the Barbary to get a packed room of party people loose to a new school mixture of dance party music.   In the last few months, they have had groups like Yo! Magesty and DJs like LA Riots. This month they are partnering up with Vice Magazine and Colt 45 to bring New York's Drop The Lime aka Curses! down to rock the party.   
4AM @ The Barbary (951 Frankford Ave.) - Friday June 6th - 10pm - 2am - Free 
Of course, The Roots Picnic is the biggest party in Philly this weekend. The worlds greatest hiphop band, The Roots, have brought some of the best most buzzed about artists to Philly. Gnarls Barkley, Sharon Jones & The Dap Kings, J*Davey, Esperanza Spalding, and many more. It all goes down over at the Festival Pier at Penns Landing this Saturday afternoon at 2pm. But just to make this event bigger, they just added a pre-concert jam session Friday night at the Filmore at TLA featuring The Randy Watson Experience (?uestlove, James Poyser, Bilal and Robert Glasper), Santogold, Janelle Monae, and of course, The Roots. This is not to be missed.
Hors D'Oevres Pre-Picnic Jam Session @ Filmore at the TLA (4th & South St.) - Friday June 6th - 11pm-2am - $35
The Root Picnic @ The Festival Pier (Columbus Blvd and Spring Garden St.) - Saturday June 7th - Starts at 2pm - $39-$49
On Sunday, we know people are flocking north for the Philadelphia Bike Race and south for the Odunde Festival, but for those of us that need to get crunk, head to 12th and Spring GardenDiplo and his Mad Decent label are throwing a block party with some the best of the best of the hipster/hollertronix (for lack of better term) scene. The long list of talent includes Flosstrodomus, DJ Blaqstarr, Dj Sega, and many more. 
Mad Decent Block Party @ 12th & Spring Garden St. - Sunday June 8th - 12pm - 8pm - Free
