The latest macho man aching to play both thug and Romeo is the R&B singer-songwriter Tank, a.k.a. Durrell Babbs. Celebrating wild women in songs like "My Freak," Tank goes where many have gone before. But despite the pose he manages to tell familiar stories in intriguingly new ways, particularly on his hit single "Maybe I Deserve," whose droning, minimalist melody backs up a painstaking lyrical inventory of the costs of romantic mistakes. With his baritone barely rising above conversational tone, Tank makes you feel his pain with an understated ache.
