While I am always open to finding excellent recordings for the purpose of this thread lets stick to recorded in one take and minimally mixed. If not things get too confusing.
I do like progressive music but I just mentioned it as an example of the type of music that is not recorded correctly (for this thread). That is why I mentioned
Jazz,
Bluegrass, Blues or Classical.
Narrowing it down more I will say Jazz and Classical. There should be a lot of old school recordings of these. Its just a matter of finding the good ones.
There have been some good recommendation so far and I have a couple of new albums coming. But finding the exact release mentioned, having it in stock and making sure it is not a CD-R copy is the challenging part.
