His “Rhapsody in Blue” of 1924 quickly turned out to be a hit with the public, and so the New Yorker George Gershwin, inspired by such success, followed it up only one year later with a Piano Concerto in F. With its ingenious mixture of classical form and jazzy sound, this piece also became an international success. “Since then, these two works by Gershwin have come to fundamentally embody the essence of American music,” says Jean-Yves Thibaudet. And swing is central to this music: “If you don’t swing, you don’t play the Concerto in F. It quite clearly has a foot in each camp, and I like this ambiguity.” The second work in this concert programme is also ambiguous. It was the great conductor Otto Klemperer who persuaded Arnold Schoenberg in Los Angeles in 1937 to orchestrate Brahms’ G minor Piano Quartet. Here, Romanticism is cloaked in the sound world of a twelve-tone musician. “All I had to do was transfer this sound to the orchestra, and that’s all I did,” Schönberg said with typical understatement. However, Otto Klemperer was deeply impressed and full of praise: “One doesn‘t even want to hear the original quartet any more, the arrangement sounds so beautiful.”
