Annie Lennox’s solo hits reaffirm what a singular presence she is in pop. Her voice—informed by R&B and folk, but with the passion of gospel—is as light and soulful as it is stern and dramatic, and it's most often set as a fiery phoenix against icy synth-pop. She swoops from the jittery recrimination of “Walking On Broken Glass” to the icy beatitudes of “Love Song for a Vampire” and the utter heartbreak of “Why” with the same emotional commitment.
