Grieg worked on a transcription of the concerto for two solo pianos, which was completed by Károly Thern. The premiere recording of this version was by the British piano duo Anthony Goldstone and Caroline Clemmow. On April 2, 1951, the Russian-born American pianist Simon Barere collapsed while playing the first few bars of the concerto, in a performance with conductor Eugene Ormandy and the Philadelphia Orchestra at Carnegie Hall in New York. He died backstage shortly afterwards. It was to have been Barere's first performance of the work.
