It's a recording that just a few years ago would have been mainstream: a "name" pianist (albeit one much less well known in the U.S. than elsehwere), who has been playing Mozart's piano concertos since childhood, joins forces with a name conductor with whom she has frequently collaborated, leading a modern-instrument orchestra of some 70 players, with the results released on a major international-conglomerate label. Now it's distinctly unusual. But lo, there's value in the old ways. Portuguese-Brazilian pianist Maria-João Pires is a lifelong Mozart specialist, but she still has new things to say in two of Mozart's most popular piano concertos. You can chalk it up to her Buddhist outlook if you like: her readings of the Piano Concerto No. 27 in B flat major, K. 595, and Piano Concerto No. 20 in D minor, K. 466, might be described as detached without being lifeless. Her approach is most startling in the Piano Concerto No. 20, where her no-drama shaping of the material runs sharply counter to type. Sample the piano's entrance in the first movement, where it offers a twisting, tense elaboration of the main theme that is far removed from its source material. Generally pianists use this to raise the tension level, but Pires lets the unusually shaped, chromatic line speak for itself with fine effect.
