Practice makes....better!

Music can be an imperfect art. There are no boundaries or limits that you have to play within. In fact many artists learn new sounds by accident and later on include it in playing. The reason I bring this up is to remind blues guitarists that we have a sound of our own. Some blues guitar is clean and very good, but most are pretty dirty heavy sounds. Use your imagination when playing and try new things even if they are uncomfortable. Look up a few of these artists for some inspiration: Stevie Ray Vaughan, Jimi Hendrix, Buddy Guy, Freddie King, Albert King, John Mayer, B.B. King.
