To start with, Doyle Bramhall and Doyle Bramhall II are father and son. The cd you picked up "fitchburg street" is the lateset release from the elder Bramhall. He also wrote and sang with Stevie Ray Vaughn.  Doyle II was an original member of the Arc Angels and was also with the Fabulous Thunderbirds. He is currently working with Clapton. IMO, his music is much better than his father's.
