"Although Argerich has participated in numerous musical partnerships, not to mention her longtime mentoring of young artists, her associations with violinist Gidon Kremer and cellist Mischa Maisky are surely among the pianist's most substantial and musically rewarding collaborations. The present collection includes all of the Argerich/Kremer and Argerich/Maisky duo recordings for Deutsche Grammophon as originally released and in chronological order, allowing listeners the opportunity to trace each duo's evolution in terms of artistic rapport, sensitivity, risk-taking and the fine tuning of nuance.

Initially Argerich expressed apprehension about recording Beethoven, lest her readings might sound self-conscious under the microphone's objective, unforgiving scrutiny. Yet, during an interview conducted prior to the cycle's final sessions, both Argerich and Kremer spoke of using the recording
