Almost any release on the ECM jazz/new music, label.
From their earliest in the early 70’s, up through their current releases.
Even with their studio recordings, there is a very real sense of real musicians, all playing at the same time, in the same acoustic space.
Also, they used very high quality vinyl on their original releases, so they were dead quiet. I’ve also noticed with used copies I have bought recently, a very high percentage of them seem to be in very good condition.
On their CD releases, they never fell into any bad digital habits, like: excessive compression, noise gating, etc. Their CD’s are consistently very good.
And musically, extremely good. Creative without being on the extreme avant-garde side. They always seem to find lesser known musicians, with world class chops.
A very easy label to buy blind.
And let me add, they hardly ever sound like they are trying to be a 'jazz nostalgia' label. They always seem to artists with a fresh take on jazz.
