Sergio Mendoza is one of the great innovators of the Arizona music scene. He’s a composer, arranger, producer and programmer who plays keyboards, guitar, percussion and horns, and works with the fine American band Calexico. He may be based in Tucson, but his inspiration comes from south of a border that is not blocked by any walls. With Orkesta Mendoza he sets out to update and enliven the Latin big band tradition, mixing influences from Mexico and across Latin America with electronica, strings and unexpected bursts of western pop. He has a sometimes brash, widescreen style that would have impressed Phil Spector, but there is impressive variety in his exuberant approach. So he starts with stomping, brassy dance songs, slows down a little for a grand, piano-backed ballad and then changes direction again for Mapache, with its witty reference to 60s instrumental pop. Classy and enormous fun.
