On a semi-regular basis, Fret Killer posts videos of a very eclectic set of songs all played on his acoustic guitar. All the videos are done in the same manner: all you see is the guitar and his fingers literally killing the fret board. Here are a couple of favorites of mine:
Ain't She Sweet (as of this entry, his latest post)
You Don't Mess Around With Jim (Jim Croce song)
My Back Pages (Dylan Song)
It's a Sin to Tell a Lie (an old 1920's tune)
With that, I've listened to/ watched everything he's posted and they're all great.
Only 2 beefs with Fret Killer: 1. he remains entirely anonymous, as far as I know. I would pay to see this guy in concert. 2. He disallows embedding of his videos (thus the awkward linking above).
In any event, check out his stuff...it's worth the time.
