Here are a few (no doubt people will add to this list):
(My subjective taste, on decreasing order):
1. Arthur Rubinstein (RCA - Arguably the best interpreter of the nocturnes, perfectly capturing the emotional and lyrical character of these pieces).
2. Claudio Arrau (Phillips – A really deep and spiritual rendering of the nocturnes, making an intriguing contrast with Rubinstein above. Highly recommended)
3. Alfred Cortot (while Rubinstein was emotional, Arrau spiritual, Cortot is poetic. No one phrases Chopin like Cortot)
4. Ignaz Friedmann (Pretty wonderful.)
5. Adrzej Wasowski (Concord Classics)
6. Ivan Moravec (WEA – some people consider this the best ever recorded set of the Nocturnes).
7. Maria João Pires (DG – Beautiful interpretations totally devoid of sentimentality)
8. Tamas Vasary (DG - Although very underrated, Vasary is one of may favourite Chopin interpreters).
On the other hand, Pollini, Ashkenazy, and Baremboin left me completely indifferent.
Best wishes,
Bernhard.
