There’s more to this modern block than the ultra splashy Radisson SAS hotel and the Sea Life aquarium. A sunny terrace café faces the Spree River and gift shops front its Karl-Liebknecht-Straße side. Through May 7, the gallery Schoen + Nalepa (entrance St. Wolfgang Str. 2) presents the works of Nikolai Makarov, a Moscow-born artist who now makes his homes in Berlin and New York. His meditative work has been poetically linked to composer John Cage: “John Cage taught us to hear silence – Nikolai Makarov lets us see it.”
