Jazz vocalist Kellye Gray, R&B star Lalah Hathaway and rock band Luce are among the headliners set for the 12th annual Art and Soul Oakland. The two-day festival, set for Aug. 4 to 5 in downtown Oakland, will also feature hip-hop collective Hieroglyphics, gospel's Edwin Hawkins Singers Art and folk-rockers Blame Sally in a lineup that heavily favors local talent.

The event -- the City of Oakland's flagship festival -- also has some new tricks set for festivalgoers this year. Notably, it's expanding to include a late-night bash on Aug. 4, which will include audio-video art installations and multimedia performances to accompany DJ Dyloot broadcasting from the rooftop of Oakland City Hall.

Also, this year's festival will include a cutting-edge art show. The exhibit will feature collaborations with de Young Artist Fellow and Artist-in-Residence Alumni, Ex'pression College for Digital Arts, and Black Rock Arts Foundation, the nonprofit arts organization that supports Burning Man art and artists. There will also be work from Oakland-based arts collectives the Crucible and NIMBY, as well as from artists from American Steel.

Much of the art will be on display on racks located in the walkway between Frank Ogawa Plaza and City Center.

The festival runs from 2 p.m. to midnight on Aug. 4 and from noon to 6 p.m. on Aug. 5 and is centered in Frank Ogawa Plaza and City Center, encompassing 10 easy-to-walk city blocks.
