The 57-year-old orchestra—led this weekend by violin head Jeffrey Multer—is performing all of Antonio Vivaldi’s 18th century magnum opus. The first half of the Masterworks Series performance will feature Mozart’s 39th symphony in E-flat, because the two composers would have walked the earth at the same time, had Vivaldi lived another 15-or-so years. Saturday at Mahaffey is sold-out so your best chance comes thanks to Ybor’s Centro Asturiano which also hosting the orchestra on Friday night.—Josh Bradley
