Some videos, that are worth seeing. The blues is not necessarily associated with feeling upset.
Feel so good -- Dr Isaiah Ross
Poor boy long way from home -- Booker White
(I'm pretty sure this is actually Bukka White, using another name.)
Terraplane blues -- Michael Pickett (cover)
I just had to put these out there... Enjoy!
All credit and respect to the musicians. This is incredible footage. Obviously, it is not my own. I would encourage everyone to go out, and try listening to the blues.
