Watch the Performance Studies online guitar lesson by TrueFire from Play Blues Guitar 8: Advanced Rhythm Approaches
In section 2 you'll cover some really important blues feels like a minor blues, a jazz blues, and some funk. Being able to have a good command of different styles and grooves is what sets great players apart, and once you have all these under your fingers you should be ready for anything!
TIP! One of the best pieces of advice I ever got as a player, was to "learn it - then do it your own way". At first that seems counter-intuitive. Afterall we are trying to really nail the lessons we are working on, and once we do that… then we are supposed to change it? YES! Throughout history players have been borrowing, or outright stealing others licks and ideas, and then changing them to make them their own. Basically you have to start somewhere as you are developing your own voice on the guitar, so it makes sense to learn something that is already pretty cool, and then put your own spin on it. Try it out, learn a new lick or pattern, but then instead of just moving on to something else - look at how you can tweak, adapt, extend, change and make it your own.
