Classical CD-guide in print or on web?


How do Audiogoners decide which recording to buy of a a classical music piece? I know there is the Good Classical CD Guide from British Grammophone magazine, but astheir customer service is awful, I haven't reveived it yet after ordering it three times. Are there other resources, maybe on the web, which compare recordings, and tell you which ones are the best?

The Basic Record Library book offered by Performance Today, the NPR radio program is a nice starter.

Hassel, may I suggest that you hold off on purchase until you become aware, reviews, listening to 1 minute clips on Tower's site, and reading the chat sites here and over at Gramophone.com. I've got lots of disc's I find "not up to the music".
The best resource on the Internet is the newsgroup rec.audio.classical.recordings. Best way to find a recommendation for a particular piece is to try the google search on the newsgroup. There are some really knowledgeable people who post to that newsgroup and you can learn a lot by simply reading their comments.
