Below are reviews of the most highly regarded recordings for this pairing: 1. Murray Perahia & English Chamber Orchestra

His reading of No. 24 is described as "deep" and "multi-layered," avoiding the "clipped" feel found in less successful versions. Mozart Piano Concertos Nos 20 & 21 - Gramophone

Widely considered a reference recording for these works, Perahia's cycle on Sony/CBS is praised for its "precision, clarity of expression, and beauty of sound".

Reviewers highlight her "thoughtful and mature accounts" where every note matters. Her approach to No. 24 is described as conveying an "ineffable sadness" with subtle withdrawals of tone.

The slow movement of No. 21 is described as "magical," while the C minor concerto (No. 24) is delivered with "fluency and strength".

Perahia is noted for his "delicate" touch compared to other masters, with a gift for reducing his voice to a whisper while remaining eloquent.

2. Mitsuko Uchida & English Chamber Orchestra (or Cleveland Orchestra)
