"Soul Sacrifice," prepare to "Fade to Black."

Carlos Santana will trade licks with Metallica axeman Kirk Hammett next month during "SOTA at the Fillmore," a concert to raise funds for the San Francisco School of the Arts.

The event will be held at San Francisco's legendary Fillmore auditorium on April 4. Santana, who played a similar benefit gig for SOTA last year, will be backed by his touring band's bassist, Benny Rietveld, along with the school's concert orchestra.

Hammett, who's enjoying some downtime before work commences on the next Metallica record later this spring, is slated to take the stage and pitch in on three, as yet-undetermined tracks. Actor/comedian Cheech Marin will MC the show.

Santana and Hammett have tentative plans to rehearse for the gig on April 2, according to a publicist for the event, and they will likely decide which songs they'll perform at that time.

The San Francisco School of the Arts is the only publicly funded high school in the Bay Area, with an enrollment of around 400 students studying programs in music, dance, theatre arts, film and visual arts.
