Stubby, you may already have run across this, but this is a fun Jimmy Herring show, and the sound is surprisingly good for Youtube. Someone got a board feed.

Opens with a blistering cover of "Within You Without You" and gets awesomer from there. Offers something for everyone, if you define "everyone" as guitar fusion nerds - there are Beckisms, Holdsworthisms, McLaughlinisms, Mississippi Delta-bluesisms, Ganges-Delta-Blues-isms, and all manner of other nifty things.
The only drawback to the video, if there is one, is that it is pretty much a static closeup of Herring's guitar playing, or a static shot of whoever is soloing - you can hear but not see his interaction with his band. Which is kind of a shame to miss out on. Of course, there's only so much one dude with one camera can do at a festival show, so it's not a complaint - it's just an "I wish".
