On March 7, 2010 Karen returns to the political cabaret of her Berlin roots and flexes her revolutionary artist muscle in Foreign Currency: Political Cabaret for Our Time, at Joe’s Pub in NYC with Doug Oberhamer (piano) and Gregory Chudzik (bass). The show was originally conceived for the BKA Theater in Berlin in 2005 as an homage to Marlene Dietrich.

On September 15, 2010, Karen joins the cast of Jacques Brel Returns, with performances running through the end of the year at the Triad Theater, NYC with Rick Hip-Flores on piano and including fellow singers Jean Brassard, Ereni Sevasti, Robert Cuccioli and Gay Marshall among others.
