Our guest is Ron Spigelman, who will conduct the Tulsa Symphony Orchestra during its next concert (happening tomorrow night, Saturday the 5th, at the Tulsa PAC). Opening with Rimsky-Korsakov's vivid "Capriccio Espagnol," the evening will also feature Mozart's "Posthorn Symphony" (or Serenade No. 9) and Debussy's swirling and colorful "Images." More info is posted here.
