is taking it all off for her friend Brett Dennen – or at least her shoes.
The actress just finished shooting the music video to Dennen's new single "Make You Crazy." Dennen, a guitarist from California, teamed with Afro-beat legend Femi Kuti for the song, which last week became the third-most added single across tastemaker stations, behind Ryan Adams's "Fix It" and The Killers' "Human."
The "Make You Crazy" video is about freeing oneself from constraints and being true to oneself. In it, Dennen plays a barefoot shoe-store clerk who is trying to help a difficult customer (Moore). After going through too many pairs, Moore decides she wants to follow Dennen's trend and strips off her own shoes.
The video is set to debut around the same time as Dennen's new album, Hope for the Hopeless
, on October 21. Dennen will follow the release with a "mini-tour" on Nov. 3 and a headlining tour early next year.
Moore, meanwhile, is wrapping up some vacation time on the east coast. She wrote on her celebrity MySpace page
that she went to New York "to do some writing, see some friends and a few shows." She went up to Boston on Saturday and performed with pals Mike Viola and Lori McKenna.
Next, Moore is heading back to LA to record some of her new songs and dive "into a few other new projects," she writes.
