Rock the Bells 2009

The touring hip-hop mega-festival returns to Merriweather Post Pavilion on July 12. With a line-up that includes a heavy does of mid '90s heavyweights, this year's show is sure to be the finest hip-hop concert we'll see this summer. Wondering if there's enough artists to justify the ticket price? Well, we've put together a preview of this year's artists to help you make that decision.—Jason Schellhardt
