The miracle is not that each succeeding disc of Vivaldi concertos by Europa Galante led by Fabio Biondi is as brilliant as the preceding discs. The miracle is not that for each succeeding disc that Biondi finds more first-rate Vivaldi concertos. The miracle is that, with so many gracefully charming, elegantly witty, and delightfully diverse concertos to chose from, that only Vivaldi's Four Seasons have become the musical wallpaper of elevators and airlines throughout the world.
