Vivaldi wrote hundreds of violin concertos, yet even this tiny sample of six, written during the composer’s visit to Prague between 1730 and 1731, demonstrates in every movement his genius of harmonic and dramatic surprise. Each concerto is startlingly original, from the opening movement of the E Minor RV 278 that pits daring solo passages against a hypnotic, pulsing orchestra, while the same concerto’s Largo even feels modern in its angularity. A more familiar Vivaldi can be heard in the C Major RV 186, with its Italianate innocence and winsome middle Largo. But whatever the composer’s mood, Fabio Biondi and Europa Galante thrill to his ingenuity at every step.
