With her guttural punk growl, Patti Smith can make any song seethe. Snarling rock burners like "Boy Cried Wolf" and the grungy, atmospheric elegy "About a Boy" find the laureate embracing her poetic gifts and witchy charm. She casts just as much power over other people's songs too, giving The Rolling Stones' "Gimme Shelter" a touch of her visceral quiver and Nirvana's "Smells Like Teen Spirit" an eerie dusting of twang.
