Original Broadway Cast, 2011 (Masterworks Broadway) (3 / 5) If you’re looking for an under-the-radar guilty pleasure album, you could do worse than Wonderland. It’s the silliest and least self-important of Frank Wildhorn’s scores, and the first act especially is a wacky delight. “We’re all a little nuts, in case you didn’t know,” the denizens of Wonderland tell an all-grown-up Alice (Janet Dacal) in this unconvincing twist on Lewis Carroll (please don’t listen for the plot), and the music is a little nuts, too. The Wonderland setting  and the panoply of fantasy characters allow Wildhorn to pastiche any style he can think of: there’s a soulful caterpillar (E. Clayton Cornelious), a pop salsa-dancing Cheshire Cat called El Gato (Jose Llana), and a boy band-fronting White Knight (Darren Ritchie). Their trio of songs, which come back-to-back-to-back early on the album, are well-made, playful, and fun. Dacal, whose Alice communicates exclusively through a pop belt dialed up to 11, is always an appealing vocal presence, especially in the aggressively catchy “Through the Looking Glass.” They’re all overshadowed, though, by the extraordinary Kate Shindle (before her election to the presidency of Actors’ Equity) as an electrifyingly villainous Mad Hatter who screlts to bring the chandelier down. The versatile orchestrations, by Wildhorn’s frequent collaborator Kim Scharnberg, are a hoot. Alas, the second act is an unoriginal slog until the finale, “Finding Wonderland,” which recalls The Wiz’s “Home” (as opposed to this show’s sweet opening number, also called “Home”) and showcases Dacal’s substantial gifts. — Dan Rubins
