Two very different interpretations of the Nocturnes by Frederic Chopin.

The music is warm, compassionate and yearning; Chopin is dreaming in the moonlit garden.

The music is dark and moody; Chopin is sulking in his room. From the liner notes:
'I am up to my neck in evening parties, concerts and dances, but they bore me to death; I am sad, and feel so lonely and forsaken here. I must dress, appear with a cheerful countenance in the salons; but when I am again in my room, I give vent to my feelings on the piano, to which, as my best friend in Vienna, I disclose all my sufferings.'
Thanks to R Browne and CSI for the Kenny Barron recommendations; I'll give them a listen.
