Watch the Big Rock: Rhythm online guitar lesson by Jeff McErlain from Blues-Rock Evolution
According to Benjamin Franklin, "originality is the art of concealing our sources." We all have our influences, and while it can be hard to get away from them, at some point you need to have your own voice, just like the people we look up to did.
Although I can almost always trace my licks and concepts back to somebody else, I try to take what came before me and make it my own. Steal what you can, then let it stew.
