Maria Joao Pires was born in Lisbon in 1944. All the recordings are recent and the sound quality is excellent. Her recordings of the Chopin Nocturnes inspired a lot of five star reviews. I own those as well, and I think the raptorous reviews for those are justified. You may want to read them- you will be treated to similar music here.Here is what the liner notes say for these CDs: "Her philosophy begins and ends in the self-controlled fervour of her almost maternal concern for the well-being of a work's inherent character, and, ultimately, her knowledge and skills all go to serve nothing more or less than the natural simplicity of musical invention." Needless to say, we would hope for that style, given these stellar works from Bach, Mozart, Chopin etc. I give four stars in an effort to control "star inflation". There is nothing disappointing about these CDs.
