[Schubert:] With his well-nigh perfect technique, Quasthoff produces his tone throughout the registers with no audible strain, evenly, unfettered. Then his speeds always seem the just ones, phrasing is seamless and long-breathed, the emotions projected from the musical arch he creates.

[Brahms:] With all his superb control of all aspects of his performances, Quasthoff convinces me through his sincerity and his strength of purpose, and of course he and the faultless and technically assured Zeyen are much better recorded than any of their predecessors. Anyone who wants this discerningly chosen match of works need not hesitate.
