LaPlace Elementary School students were summoned into an assembly on Oct. 30 to receive a $30,000 grant from Toyota and VH1 Save the Music. The money will pay for a new music program, the first at the school since Hurricane Katrina. It’s big news, but the students might have been more excited — at least for the moment — about the star who came along to deliver the check. Internationally known singer-songwriter Santigold, in town to perform at the Voodoo music festival, made a special appearance, wearing a giant hair bow, singing for the students and calling energetic young fans up onstage with her.
