abstract:Lambert Orkis (born 1946 in Philadelphia, PA) is a United States-based pianist of classical music. He excels - among other points - by a particular many-sidedness: on the one hand, he has acted since 1988 as the performance partner of Anne-Sophie Mutter in their concerts of piano and violin chamber music (mainly containing sonatas for violin and piano by Beethoven, Mozart, Brahms, and Schubert).
