The good news: music lovers unfamiliar with Gilbert Castellanos are in for a surprise, maybe an epiphany. The San Diegan's a world-class trumpet player featured in Richard Montoya's tribute to local jazz and Latino roots. The difficult news: the world premiere currently exceeds its grasp with overlong scenes and stencil-thin characters, and Castellanos isn't featured enough. The multimedia piece often reveals unknown parts of San Diego history. But in many ways Federal Jazz Project is about Montoya. He controls the narrative and does much more telling than showing. If he were a point guard, he takes too many shots and should drop more dimes on his teammates, the remarkable Castellanos most of all.
