This is the first solo work by Charlemagne Palestine on Sub Rosa from Etudes to Cataclysms is one of Charlemagne's most important works. An impressive composition of more than 140 minutes based on a unique instrument - a double piano on which one keyboard is played by the feet. "Several years ago, Martin Kaufmann of Kaufmann Pianos in Brussels told me he had seen and heard an amazing and unique instrument in Italy. A piano with two separate bodies! One with a normal grand piano body having 88 notes to be played with the fingers, and below this piano was a second piano also with a grand piano body that could play simultaneously the lower 37 notes of a grand piano with pedals for the feet.
