A previously unknown work by young Wolfgang Amadeus Mozart was recently discovered among old printed music in an attic (more on the story here).
The sonata was performed yesterday morning in one of the Mozart family apartments, now a museum, in Salzburg. Here is a recording of part of the newly discovered sonata, played by Florian Birsak on Mozart’s own Hammerklavier ( — click the play icon on the audio bar, found a few lines below the image of the manuscript).
It definitely sounds like young Mozart to me — lots of virtuoso noise and then an arching, achingly pretty melody above it. No one else wrote like that at the time, he was already in a category by himself.
