A torch passes. The Minnesota Orchestra’s Golden Age under the Finnish maestro Osmo Vänska, repeatedly extended, is history now. And the love match with his Danish successor Thomas Søndergård is just beginning. As music director designate, Søndergård celebrates Paris in the early 20th century. His program opens unseasonably with “Of a Spring Morning,” the swan song of the short-lived Lili Boulanger (1893-1918), talented younger sister of the celebrated Nadia, muse to whole generations of modern composers. Next up is Ravel’s fairy-dusted Mother Goose in its fleet entirety. To close, again unseasonably, there’s the Big Bang of Stravinsky’s The Rite of Spring (1913), a classic destined never to cease to reset the clock. —Matthew Gurewitsch
