Karl Böhm (1894-1981), one of the leading conductors of the 20th century, has left an impressive number of recordings through his exclusive cooperation with Unitel. In the mid-1960s until his death, a large part of Böhm's work as a conductor was recorded on video and is still preserved today.
Under the baton of Karl Böhm, the Wiener Symphoniker perform Beethoven's Piano Concerto No. 4 in G major together with the piano virtuoso Wilhelm Backhaus, who was over 80 years old at that time.
