Mitsuko Uchida and Mark Steinberg play Mozart Violin and Piano Sonatas. The image says: Something’s going on here. These are people with something to say. Doesn’t matter whether the image evokes Mozart or not. The playing in fact is focused, inward, individual, sometimes sharp (with an edge), sometimes ferocious, not untroubled. So the image is accurate. It really does tell you — without words, without any thoughts it might be easy to name — why you want to hear this CD.
