With BottleRock just about ready to boom, Napa’s other wide-eyed fest, the Napa Valley Film Festival, is getting in on the action early with some music-centric sneak peak screenings. Monday, May 6, taps the organization’s alliance with BottleRock for a fundraiser/screening and Q&A of the documentary Sound City, Dave Grohl’s (of Nirvana and Foo Fighters fame, who will be in attendance) directorial debut. Tuesday, Sundance favorite Twenty Feet from Stardom will get its Napa debut at the building formerly known as COPIA. Music is also on the mind in this flick, which brings the stars-behind-the-stars to the forefront. Rock legends like Sting, The Boss and Mick Jagger wax about how below-the-radar backup singers like Darlene Love, Lisa Fischer and Judith Hill (now forging her own tracks on Season 4 of The Voice) helped define the sounds of the time. Director Morgan Neville will be on hand for Q&As after both screenings, and Fischer, making a pit stop off her tour with the Rolling Stones, will perform live following the 5:30PM screening. Looks like Napa is most definitely ready to rock. The 5:30pm screening is $20 and includes a wine tasting; 8:30pm screening is $10. 500 First Street, Napa, www.nvff.com.
