Marinate a voice box in fine wine, wrap it in silk and install it in Michael Monge … actually, don’t bother. Nature already did. Smooth and swingin’, this ex-Bronx car-repair-shop owner’s Vegas-style Cinder-fella story—plucked from NowhereVille when Steve Wynn caught his set at a Florida restaurant and recruited him posthaste—only deepens appreciation of his talents. Whether he’s belting Sinatra-style on “The Lady Is a Tramp” or lending his own chic interpretation to a Billy Joel or John Legend signature tune, Monge is a boomerang back to old-school class—it’s in his sound, in his style, in his presence. 9 p.m.-1 a.m., Wed-Sun, Eastside Lounge at the Wynn, $10 cover charge, one-drink minimum, 702-777-9966, WynnLasVegas.com.
