Theater Latté Da is bringing Stephen Sondheim’s A Little Night Music to the cozy quarters of the Ritz Theater. Based on the Ingmar Bergman film Smiles of a Summer Night, A Little Night Music concerns the entangled relationships of Desirée Armfeldt, a bewitching actress who has eschewed domesticity in favor of the heightened passions of the stage. Weary of endless tours and fleeting affairs, however, the actress is reconsidering her perspective, particularly in regards to Fredrik Egerman, an accomplished lawyer and former lover. Never mind that Frederik is currently committed to a frustratingly chaste marriage with the much younger Anne, or that Desirée’s latest paramour, Count Carl-Magnus Malcolm, is obsessing over her every move. Such imbroglios only scratch the surface of a work in which every character harbors a secret infatuation, to be passionately revealed through song. Two of the Twin Cities’ most acclaimed talents, Sally Wingert and Mark Benninghofen, headline the production under the assured direction of Peter Rothstein.
