When it comes to the blues today, there are a handful of guiding lights to make sure the music stays true to its powerful source. The sound of pleasure and pain that first sparked musicians to create such a sound is a force that can never be underestimated. The mojo has to be there. For Jimmie Vaughan, he's dedicated his life to making sure the blues not only stays alive, but remains full of life and an inspiration to all who listen. It's a spirit he holds close to him, and for over 50 years of holding the blues close inside him, Vaughan isn't about to stop now.
