Beethoven - 1. Klavierkonzert, op. 15

Confusing as it may be: Ludwig van Beethoven's Second Piano Concerto was in fact composed ten years prior to his First Piano Concerto. The cause of this mess lies with the composer himself: Beethoven held back the publication of what we know as the Second Piano Concerto until after that of the First Piano Concerto, so he could thoroughly review the piece. Together with his septet and First Symphony, this piano concerto was finally performed at his official Vienna debut on April 2, 1800 at the Hofburg theatre, with Beethoven himself at the piano. The composer had long ceased to be an unknown in Austria's capital: he had been playing private concerts all around town for years.
