As you may have already heard, Rock the Bells took over Governors Island this weekend and delivered legends dropping classics. Aside from Lauryn Hill, that meant Snoop, KRS-One, A Tribe Called Quest, Slick Rick, and Wu-Tang Clan. Over in L.A., the Sunset Strip Music Festival presented Common, Kid Cudi, Smashing Pumpkins, Michael Franti, and Slash rocking with, um, Fergie. Justin Bieber kept the hip-hop vibe going — Yes, we said "Justin Bieber kept the hip-hop vibe going." Have you not heard his Kanye-Raekwon collaboration?! — over at the Prudential Center in Jersey. But the weekend's winners? Anyone smart enough to check out the last ever Williamsburg Waterfront show, where Delorean was joined onstage by surprise guests Andrew W.K., Doug E. Fresh, DMC, Les Savy Fav's Tim Harrington, and freakin' Gucci Mane. She & Him, Michael Franti, and Thurston Moore are in our concert photo roundup as well, but that's not as exciting as surprise Gucci Mane, now is it?
