This Sunday night on “The Lost Chord,” steal some fascinating glimpses of Béla Bartók at the piano, captured in rare, private recordings, preserved on wax cylinders and archival 78s.

We’ll hear Bartók perform some of his own music, including fragments of the Piano Concerto No. 2, with Ernest Ansermet conducting. He’ll also be the soloist in works for keyboard and orchestra by Bach and Mozart; Ernő Dohnányi will direct the Budapest Philharmonic. Music by Beethoven and Brahms will also be featured. As an added bonus, we’ll get to hear Bartók speak, in English, at a 1944 concert given by his wife, Ditta.

Hungary for Bartók? The snacks are on wax. Join me for “Saving Private Bartók,” this Sunday night at 10:00 EST, on WWFM – The Classical Network and wwfm.org.
