What do you give the technology-idolizing age that has everything? How about an entire album of original, acoustic gospel blues, sung and played with a true believer’s late-night intimacy with life’s big ups and downs? Cut it anywhere, it bleeds the truth. “My God came to earth a humble man,” sings Phelps. “It was part of the divine master plan. When they crucified our Savior, they set the captives free. / Death would lose dominion over you and over me.” So far, there’s no app for that.
