What is your source for discovering new music?

Listing sources in no particular order:

Fellow members of the Houston Audio Society

Amazon.com
Audiogoners
Pandora
Reviews particularly equipment reviews where the reviewer used certain albums to evaluate the equipment in question.

Last but not least I keep going back to the thread I created on Audiogon way back in 2003 which has till today received 200 responses. This thread is brimming with some fabulous music and can be a great resource for any music lover who is looking to find interesting music to discover. I am providing the link here for you to check out. I hope it will prove useful.

HDTracks, and ITunes. Treat myself when I hav a real good day at work. Took me forever to get out of habit of buying album, keep tryin' new tunes till I hit one says "yeah". After couple days maybe come back buy rest.

(1) New release emails from H&B Direct.
(2) Pandora. Quality is low, but it's OK at the office.

I have to be very selective what I buy now, I am overflowing with software, with nowhere else to put them.
1) I agree with Tom6897 list of labels to look for, but would add ECM and Stockfisch. Buy almost anything on ECM and there is a lot, great recording and artists and a knack for throwing odd artists together. There is a wonderful recent CD called Officium, pairing Jan Garbarek's Jazz saxophone with the Hilliard ensemble, an early music ensemble, it's great.

2) I agree also about Amazon, but look to user reviews and you can choose ratings as a filter in a search.

3) Of the print magazines, I find HiFi+ the best to introduce new artists

4) HiFi shows, that's one reason I go. You always find some new music being demonstrated in the rooms.

Mainly forums...music threads, and recommendations from friends. Sometimes youtube.
