Dear JDCMB readers, please get to know this piece

This is the Geistervariationen - literally, 'Ghost Variations' - by Robert Schumann, written at the end of his compositional life just before his incarceration in the asylum at Endenich. Please familiarise yourselves with it. If you read JDCMB regularly, you're going to be hearing a lot more about it in 2016.

The heavenly performance above is by Grigory Sokolov.
