American Ballet Theater comes to the Met for seven weeks this summer, a shorter run than we’re used to. Full-length ballets are what’s on offer, with one unchanging mixed-repertory program worked into the schedule (George Balanchine’s Theme and Variations, a new Alonzo King, Jessica Lang’s ZigZag). Here’s the rollout: Don Quixote, Of Love and Rage (New York premiere), Swan Lake, Mixed Rep, Swan Lake again, Mixed Rep again, and Romeo and Juliet. —Laura Jacobs
