Watch the B Minor Blues - Part 3 online guitar lesson by Jeff Scheetz from Blues Jam Survival Guide
In the performance of this one you can really see the difference between playing it really simple and open, and then when I make it more busy and funky. It totally changes the feel of the groove even though the drums and bass don't change. That is why it is so important to be aware of what you are playing. A lot of times at a jam night a guitarist will get up and not be listening to the other players and basically by his playing start taking the song in a different direction that it shouldn't go. So be careful of that! Or you may get a drum stick in the back of the head!
