A dozen discs.

FAZIL SAY, a pianist, is enjoying a well-promoted career. He's Turkish-born, in his mid-30s, energetic. He tours around with distinguished musicians such as Maxim Vengerov, the violinist. And he makes records--or CDs, if you must--which is not all that common these days. His latest is of Mozart concertos, three of them, No. 12 in A major ("the little A major"), No. 21 in C major, and No. 23 in A major (the not-little A major). Playing with him is the Zurich Chamber Orchestra, conducted by Howard Griffiths; the label is Naive--I'm not insulting it, just providing its name. Say has been affected by the "period" movement, sounding at times almost like a fortepianist. He is crisp, sprightly, clean--sometimes clipped, which is not so good. His tone can be brittle, or metallic. And middle movements might have more bloom. Occasionally he sounds like he's trying to be a good boy--stylistically correct--when he should let himself be musical. But he's a worthy pianist, stating a case. What's more, Say is a composer, writing a variety of works. This is all too lacking in musicians today. The performer/composer split is all too great. Hurrah for Fazil Say.
