Spread the news! The Vienna Philharmonic is back in the touring business. And who is leading the charge? None other than the 79-year-old Riccardo Muti, maestro of maestros, and for decades a favorite with this self-governing collective of virtuosi. Featured on the program are Mendelssohn’s concert overture Calm Sea and Prosperous Voyage, Schumann’s Symphony No. 4, and Brahms’s all-but-pastoral Symphony No. 2—a bouquet of joyous music, in short, music to raise and refresh the spirits. —M.G.
