Last year was the latest in a series of triumphant years for Theatre Latté Da. The company purchased the Ritz Theater, giving themselves a permanent home and guaranteeing that the northeast Minneapolis landmark will remain in active use as a venue for live entertainment. It was a coup, and rightly applauded. All of that, though, was built on the steady eye of Peter Rothstein. Last year, once again, he demonstrated his gifts for giving classic musicals a fresh and intimate feel, drawing on our deep well of local talent. With Gypsy, he took a show famous for its dark corners and shone a razzle-dazzle light that emphasized the material’s glorious theatricality. In the fall, by contrast, Rothstein led a gut-wrenching Ragtime that chose lean, pointed resonance over distracting stage business. It was further evidence of his ability to put the Ritz’s unique space to good use, promising many great things to come from this perfect pairing.
