Thursday-Saturday: It's a Russian program at the Minnesota Orchestra this week, conducted by Sommerfest artistic director Andrew Litton. He and his close friend and frequent collaborator, British pianist Stephen Hough, will perform Rachmaninoff's Rhapsody on a Theme of Paganini, a kaleidoscopic set of 24 variations based on a violin tune by Niccolò Paganini that gives Hough a chance to show off. This is the first time the two have performed together with the Minnesota Orchestra. Litton opens the concert with "The Rock," an early Rachmaninoff tone poem, and concludes it with the Prokofiev Fourth Symphony, in its 1947 revision, a work of heroic character.
