Any other vinyl as quiet as ECM?

Yesterday I was playing a few ECMs and Concords back-to-back.

My preliminary conclusion: Yes, the ECMs are amazingly quiet, but the Concords are amazingly dynamic. They sound the most like direct-to-disc recordings even though they were tape-based.

Great artists as well--Joe Pass and Barney Kessel, Woody Herman, the L.A. Four (Shelley Manne, Laurinda Almeida, Ray Brown, Bud Shank), Charlie Byrd, etc.

I'll look for some Concord. I'm awaiting delivery of a Joe Pass solo recording on Pablo.

Concord Jazz LP's are excellent, but if you like their musicians don't overlook their CD's of recordings originally appearing on vinyl, they are excellent as well. And I like many in their stable of performers even though they don't have the national status of the 'famous'. FWIW.
