It's a bit easier to get into the Virgin Mobile Festival this year -- as long as you're willing to pay; the "FreeFest" tickets sold out almost immediately. But $49.50 is a decent price to pay for the many hot acts, mostly of an electronic bent, in the lineup: Cut Copy, deadmau5, Cee Lo Green, TV on the Radio, Patti Smith, James Murphy (formerly of LCD Soundsystem), Calvin Harris, the Teddybears and more. Saturday, Sept. 10. Gates at 11 a.m. Merriweather Post Pavilion, 10475 Little Patuxent Parkway, Columbia, Md. Fan ePak tickets, including early admission to the grounds plus drink discounts and other souvenirs, are $49.50. Call 800-551-SEAT or visit merriweathermusic.com.
