Blacher/ Zitterbart - What About This Mr Clementi

Opinions can vary so much about the sound of a grand piano! Does it sound cold, or hollow, or full, or spiky, or dull, dry, tinny, glassy, silvery, or without any heart? It's high time to name the pianist who developed this attractive project together with his producer Andreas Spreer and performed it so brilliantly that one wants to go back to it time and again: it was Gerrit Zitterbart.
