From 2008 to 2010, St.Clair was general music director for the Komische Oper in Berlin, where he led successful new productions such as La Traviata (directed by Hans Neuenfels). He also served as general music director and chief conductor of the German National Theater and Staatskapelle (GNTS) in Weimar, Germany, where he led Wagner's Ring Cycle to critical acclaim. He was the first non-European to hold his position at the GNTS; the role also gave him the distinction of simultaneously leading one of the newest orchestras in America and one of the oldest in Europe.
