Ten different artists (Tom Waits, Cowboy Junkies, Lucinda Williams & others) sing songs by Blind Willie Johnson (1897-1945), an evangelist who thundered his gospel from the street corners of Texas. Derek Trucks regards him as one of the pre-eminent slide guitar players. The guest artists attempt to match, and sometimes achieve, the intensity of this blues legend. Surprising performances by Cowboy Junkies and Sinead O'Connor; grit from Tom Waits.
