NEW YORK.-At this time the Neue Galerie is carrying out the exhibition “Arcadia And Metropolis: Masterworks Of German Expressionism From The NatioalGalerie Berlin”  through June 7. In 1937 the Nazis seized a large collection of Expressionist works from the Kronprinzen Palace in Berlin, Germany’s first museum of contemporary art. But this branch of Berlin’s Nationalgalerie has made great strides in restoring what was the heart of its collection. This show of 40 works by Ernst Ludwig Kirchner, Karl Schmidt-Rottluff, Emil Nolde, Max Beckmann, George Grosz, Otto Dix, Hannah Hoch, Paula Modersohn-Becker and others touches on the history of German modern art — Expressionism, Dadaism, Neue Sachlichkeit — from around 1910 through the post-World War I period. Its title is drawn from the early preference of the Expressionists for rural places versus their later attraction to the city. One of the show’s great "Metropolis" paintings is Kirchner’s large "Potsdamer Platz" (1914); in the "Arcadia" mode is Modersohn-Becker’s "Kneeling Mother With Child" (1907). Satirical thrusts at the failures of the Weimar Republic by Hoch, Dix and Grosz are also standouts. Hours: Fridays, 11 a.m. to 9 p.m.; Saturdays, Sundays and Mondays, 11 a.m. to 6 p.m. Admission: $10; $7 for students and 65+
