The violinist Giuliano Carmignola is pictured on his motorbike on the cover of this collection of six concertos played "con moto", and the sound is indeed hard-driven and exciting, full of those pulsating unisons and relentless sequences with which Vivaldi powers his music. But there is also incredible delicacy and refinement here, and Carmignola's wiry sound is a world away from the tubby, rich Vivaldi performances of yore. There are countless angular surprises, one echo of Bach's Third Brandenburg, and one concerto which ignores the violin's top string, showing Vivaldi's continual inventiveness. Superb support from the Accademia Bizantina.
