Query: Exellent Music with perfect technique

This is a wonderful CD for every Schubert lover, done by a musicians working together for a long time. I, as an amateur cellist, was especially moved by the exellent music with perfect technique of Perenyi. The sound is beautiful, interpretation persuasive, tempo stable but not tedious, and music expressive. I especially like his "Arpeggione Sonata." But it's not only his music and sound that is great. As a recording of Chamber music, "ensemble" must be the priority....and this is exactly what I appreciate so much. As a ensemble group, these three are one of the best. I hope as many musicians as possibe would share their well-done work.
