Amos, (and anyone else) ..I guess we don't agree on too much...except a certain appreciation you have for the musical links, I post...so, just for you, I'll post a couple from that group(which I have a certain affiliation with), that you seem to like. I'd suggest that you buy their DVD, and play it loud, on a good, to great system...it will blow you away!!. The engineering is superb, as well as their performances!! If you noticed, the one I posted above was a Capella, no instruments! Here's a couple of more...take your time, and enjoy..
