Cruz Contreras certainly knows about life on the road.  After his first group dissolved, he hit the road again as a truck driver based in East Tennessee.  It didn't take him long to put the pieces together for his next venture, which is growing stronger every year.  With a voice compared to Randy Travis, Dan Tyminski, and even Ralph Stanley, he is leading The Black Lillies to national acclaim.  With their third studio album "Runaway Freeway Blues," they continue to leave home in Knoxville, Tennessee to play over 200 dates each year.  We had a chance to catch up with them on a swing through Nashville to hear what they're all about.
