Probably some of the best quality recordings that you can find come off of the ECM label. Manfred Eicher is a high quality producer. If you want to hear any of these before you buy them you can check them out on
www.lala.com Also, if you ever find ANY vinyl on an ECM label you should just pick it up. It's of the same quality in terms of sound as Pablo records are (amazingly good).
The Touchstones are recordings that were previously not available on CD, or so I understand. Some really good things in there. I just ordered 4 with free shipping:
Extensions - Dave Holland
Animato - John Abercrombie
Gnu High - Kenny Wheeler
Batik - Ralph Towner
