Exposé is young. Exposé is pretty. The trio's 1986 debut album, Exposure, spawned four Top 10 singles, breaking the record set by the Beatles for a debut LP, and Exposé's current disk, What You Don't Know, has produced three Top 10 singles.

So why is it that only the most ardent pop music freak can name any member of the trio Exposé? Or, for that matter, name their songs? Maybe it's because their hits, slickly produced toe-tappers like "Point of No Return" and the current "When I Looked at Him," have all the staying power of a breath mint. Or maybe it's because the group is largely an onstage front for Miami-based producer Lewis Martinee, whose skillful packaging has turned Exposé into a hit machine.

And just perhaps it's because the personnel changed, midway through the making of Exposure—one original member quit and two were fired. Their successors answer to the names Gioia Bruno, Ann Curless and Jeanette Jurado, and all were fronting club bands until Martinee hired them for Exposé II. "It still strikes me like a dream," says Jurado, 23. "When you're working in clubs, you always think, 'Someone will walk in, like me and make me a star.' And that's what happened."

The threesome's semi-anonymous stardom has meant a nonstop grind of hotel rooms and tour buses. Bruno, 24, the only one of the three who is married, worries about not spending enough time with her husband and 16-month-old daughter, Briana. Still, all three are delighted to be crashing the charts and performing as headliners—and not embarrassed to be Martinee's creation. Says Bruno: "We haven't gotten rich, but we're comfortable now." Adds Curless, 24: "We do the show, we're the magic." Concludes Jurado: "We can work a crowd and get them going. We're the real stuff."
