If you have n't seen DCB live you are missing out, I've seen him three times counting since last summer and would go again if he played within 100 miles. Perhaps the best Rock/Worship experience ever.
In the book "Body Piercing Saved My Life", the author mentions ONE worship artist who plays actual rock - David Crowder. After reading that I sought his music out. Glad I did, although he sometimes veers off into the raw strains of Texas gospel from a bygone era, he is simply the most straightforward rock artist I ever heard do worship, none of the "similar artists" in the list get close.
