But the result of that maneuvering, simply titled IV, reunites Seal and Horn for the same cinematic, futuristic R&B that defined their best work together, with a few modern touches to satisfy the hip-hop nation. And it's been successful enough thus far that Seal is supporting it with a tour -- something the poor sales of Human Being precluded -- allowing audiences to hear his gritty yet silken vocals au naturel. They remain one of pop's most influential instruments; one normally jaded Big Apple publicist, who'd just returned from Seal's performance on the Today show, sighed recently, "That voice, in person . . . I'd do him in a minute. Are you kidding?" Maybe you shouldn't wait for the live album.
