A buddy of mine loaned me the DVD of Robert Plant and The Strange Sensation in concert a while back and I finally got around to watching it and WOW! In fact, I've watched it three times.
You can find it on YT and it sounds good, but the DVD through a good system sounds awesome.
My only gripe is it is only a little over an hour long. The band is so tight you want it to run longer, but we can't sit around watching concerts all day can we!
Totally top shelf.
