I'm guessing that this has been done here before, but not for some time from what I can see.
Tell us about a performance video that just knocks your socks off and why.
Then post a link to it on youtube so that we can see (and hear) why.
I'll start.
First off, full disclosure. I 'm big fan of Jeff Beck and have been pretty much forever. So, of course I'm going to offer up a clip of Mr. Beck in action. To most, a clip of his performance at the Crossroads festival with Tal and Vinnie would be an obvious choice.
I'm going with one less obvious. He did a Les Paul tribute show in which he collaborated with Imelda May and her band. They cover "Walking in the sand" and just knock it out of the park. They horn section is great, they are swaying along to the music. Drummer Steve Rushton just kills it and Imelda's voice is as pretty and unique as she is.
Enjoy.
