Roots drummer and Twitter-fiend ?uestlove posted a video on his social networking site of choice revealing some details about the band’s third-annual Roots Picnic in its hometown of Philadelphia. The 2010 incarnation of the picnic will be held on Saturday, June 5th at Philly’s Festival Pier and feature performances by Vampire Weekend, Mayer Hawthorne, Clipse, Tuneyards, Das Racist and naturally, the Roots. ?uesto ends the video with a vague mention of a “reunion [they] thought would never happen” before donning a Run-DMC-esque gold chain & hat. Run-DMC and the Roots? We’ll see. Tickets go on sale this weekend.
