The pianist and conductor Klaus Simon was born in Überlingen am Bodensee and studied music, German and geography in Freiburg. He studied piano with Michael Leuschner and participated in masterclasses with Aloys Kontarsky (piano) and Hans Zender and Johannes Kalitzke (conducting). He founded and is the artistic director of the Holst-Sinfonietta and the Opera Factory Freiburg (known as the Young Opera Company until 2014), both of which dedicate themselves to music of the twentieth and twenty-first centuries. In Freiburg he organised a series of Lieder recitals, and as an accompanist he combines standard repertoire with less frequently heard works, including songs by Schoenberg, Pfitzner, Korngold, Alfano, Argento, Clarke and Crumb. Recently he recorded the complete songs of Schulhoff (published in three volumes, edited by Simon for Schott Music, Mainz). His recordings for Naxos include the complete songs of Pfitzner and Korngold, chamber works by Schwantner, I was looking at the Ceiling and Then I saw the Sky by John Adams, and chamber works by Martinů. In 2017 he will add to the catalogue a recording of solo and ensemble works by Steve Reich. Simon has recorded Korngold’s last stage work, Die Stumme Serenade, for cpo. Since 2007 he has worked as an arranger with Universal Edition, Vienna. His chamber ensemble arrangements of Mahler’s Symphonies Nos. 1, 4, 5 and 9 and many other smaller works for chamber orchestra are played widely throughout the world. His own recording of his arrangement of Mahler’s Symphony No. 5 with the Holst-Sinfonietta was recently released on bastille musique.
