I also like Italian ( Vivaldi, Locatelli), Spanish (Soler) and English ( Purcell) Baroque. Especially worthy of mention is Domenico Scarlatti , who, though Italian wrote most of his works (his 555 "Sonate") as a harpsichord teacher to the Spanish Infanta.
There are a couple of newsgroups devoted to classical music. The greatest is rec.music.classical , whereas rec.music.early is devoted to (yes) early music (say up to JSB).
