From Blüthner’s site:
It is with great pride and enthusiasm that Julius Blüthner Pianofortefabrik GmbH announces the addition of international jazz pianist and Grammy award winner Joey Calderazzo to the family of Blüthner artists.
Mr. Calderazzo has made significant contributions as a musical partner to such Jazz luminaries as Michael Brecker and Branford Marsalis. Mr. Calderazzo will be performing and recording with Blüthner instruments in the future. We are excited to experience the fine work of this truly singular artist.
