The Virgin Festival by Virgin Mobile in Baltimore, Md., has added a string of performers.

Modest Mouse, Velvet Revolver, Wu Tang Clan, Cheap Trick, the Fratellis, Amy Winehouse, Paolo Nutini, the Crystal Method, 311, Incubus, Chris Cornell, Ben Harper and the Innocent Criminals, Yeah Yeah Yeahs, TV on the Radio, Bad Brains and Fountains of Wayne join a bill that already includes the Police, Beastie Boys and the Smashing Pumpkins.

Completing the line-up for the second-year festival, set for Aug. 4-5 at Pimlico Race Course, are Peter Bjorn and John, Sasha and John Digweed, Danny Tenaglia, LCD Soundsystem, Booka Shade, Shout Out Out Out Out, Matisyahu, Fiction Plane, Felix Da Housecat, Miguel Migs (Petal Pusher), Spoon, Deep Dish (Dubfire + Sharam), James Zabeila, M.I.A. CSS, Regina Spektor, Interpol, Infected Mushroom, Dieselboy and Andy C, and Girl Talk.

"I feel like we came up with A list talent from top to bottom, which was our goal," says Seth Hurwitz, producer of the festival through his I.M.P. "We've evolved to where the level of talent makes for two 'A' stages instead of 'A' and 'B' stages."

The lineup is assembled "from the top down," Hurwitz says. "We didn't approach the middle and bottom parts of the bill until we saw what was above it, then we proceeded with natural sequence," he says. "Our desire was to have diversity without being directionless. It kind of reflects my personal taste: I like Patsy Cline and I like Metallica. Booking this, I try to pick the bands that are for real."

The Police are playing only one other festival in North America -- Bonnaroo. But Hurwitz says that stellar booking did not stop him from booking the best bands available. "After we booked the Police, a lot of industry insiders were whispering in my ear 'you've got the Police, you've got a free pass this year, you should save your money'," he says. "That would have made us more money this year but I look at it as an opportunity to spend money without feeling like we're taking as much risk because of this so-called 'free pass.' We're building a brand here."

Tickets, priced the same per-day as last year, go on sale May 5 as two-day passes at $175. Single-day tickets at $97.50 will only be available if the two-day tickets don't sell out.

"The Virgin people are really great and creative," Hurwitz adds. "Fortunately, this isn't just a sponsor putting a name on an event. They're very involved in the creative process, and they've just been a lot of fun to work with. We all feel like we're building something great here."
