Apparently Acman, your listening, and hearing is like Miles playing, "very advanced".
I listened to them again, and found the sound agreeable, just not enough to put money on, but I'm still listening.
Now that I'm looking and listening, I can see how enjoyable watching them on a live set could be. I went back to my first evaluation to see how, or if my thoughts on them had changed, and it has; for the better.
Enjoy the music.
