Just when you thought you had Megan Palmer pegged, she unveils "Old 33," a genre-hopping journey that shows Ohio's favorite fiddler has more than mere Americana up her sleeve. Palmer and her Hopefuls will celebrate this triumph with a happy hour show Friday at Rumba.

Previous releases found Palmer mostly dabbling in pleasant Starbucks pop with subtle traces of twang. She was by no means a one-trick pony, but lyrics like "I've been a little unpredictable/ I've been a little impulsive" from "Borderline" wouldn't have quite rang true.

Though it's no radical redefinition, "Old 33" broadens Palmer's horizons from the first moment, when leadoff track "Sideshow Sucker" frames her songbird coo with programmed drums, stand-up bass and eerie electric keyboard.

"Travel Agent" flips the script entirely with breezy country doo-wop, and from there Palmer and her players romp, stomp and sigh through 48 minutes of songwriting that puts the likes of Norah Jones to shame. It's Palmer's most diverse album and her best.
