There’s nothing like a good torch song. Even if it’s corny, it’s still good for cleansing for the tear ducts. Especially in the hands of an emotive singer, of course. I think that Duffy, despite her limited output, is one of the most outstanding torch singers in recent memory. Her voice is different; she’s not what they call a powerhouse. But her grasp of emotional nuance is above and beyond the normal diva range. Also, her tastes run retro – retro to the point of near-camp sometimes. It works, though it’s a tricky aesthetic to pull off consistently. It works because a lot of torch songs are, let’s face it, retrograde; you need a hint of irony to leverage that out.
