That's one high fidelity recording. I'm assuming it was recorded back in the 1970's when actual standards for dynamics and quality were part of studio engineering. They just don't record many of these types of intimate, up-close mixes with such distance from the quiet to loud sound in the mix. It's alive and sounds like I'm in front of them performing. Thanks for the music post. And, yeah, I have quite a nice audio system setup for my computer, so this was a treat.
