The event: A Saturday night charity event, hosted by L.A.-based fashion label Lucky Brand, to benefit the Grammy Foundation, as well as Inner City Arts, a non-profit that provides at-risk youth with access to arts-related education and programs.
The scene: Stars including Rashida Jones, Vanessa Hudgens, Parenthood actress Mae Whitman, Game of Thrones' Nathalie Emmanuel and 90210's Shenae Grimes gathered on the hills of a private waterfront home in Malibu where they sipped cocktails and listened to DJ Samantha Ronson's modernly classic mix (think old school Stevie Wonder to Justin Timberlake's "Let the Groove Get In"). Other revelers included actress Shiva Rose, singer-songwriters Aly and AJ Michalka, American Idol contestant Pia Toscano and Bravo's Dukes of Melrose star Cameron Silver.
The sounds: Ronson's music selection for the evening helped set a relaxed atmosphere for an intimate group gathered to support a positive cause for the arts. The Venice-based DJ's crowd-pleasing playlist featured mostly Motown and classic R&B, including Mo' Reese Marks' "Return of the Mack," Aaliyah's "Back & Forth," The Staple Singers' "I'll Take You There" and "Got To Give It Up" by Marvin Gaye.
At sunset, rock indie duo Tegan and Sara hit the stage where eucalyptus trees and the Pacific Ocean served as the backdrop while a gorgeous backyard pool was set in front -- they even suggested guests to jump in (No one did, of course.).
The singing sisters, who belted singles from their 2012 Heartthrob album, including "Goodbye, Goodbye," "I Was A Fool" and "Closer," delighted the crowd with stories about how they were "fairly, reasonably, well-behaved kids" because of their involvement with music and karate. As Sara told the laughing guests, "even though our mom was a single parent and struggled to make ends meet, she always forced us to go to piano lessons, which we assumed was because she wanted us to be good adults and not because she had something better to do on Tuesday nights."
When the pair's 30-minute performance ended with applause, Ronson returned to playing a few more tunes before it was time for guests to say farewell to the ocean view.
