There are levels, and there are levels. I admit on most days that I can play a guitar well enough to get by, but when I see a guitarist playing a left handed guitar with strings upside down, and it sounds this good, I wonder if I shouldn't face reality and just give it all up.
I mean - hard as it is to find someone to teach you to play left handed, imagine taking that one step further to play all your chords upside down as well. No-one teaches that.
Look at the guy with the red guitar, and witness something unique. His name is Doyle Bramhall.
