Welsh warbler Donna Lewis is a curious animal indeed. Given her proficiency with synth keyboards and her unabashed love for flowery textures, she appears to be wandering into faux-Kate Bush territory, her thoughts floating in the stars. But Lewis has a quirk that always brings her back down to earth: she's a sucker for a good hook. Remember her singsong 1996 hit"I Love You Always Forever"? This"thinking man's pop" schematic is echoed several times over on her sophomore album."Harvest Moon" functions on such a childishly simple level, it almost feels like a nursery rhyme."Falling," its rhythms bounding like Jell-O, plugs into a sunshiny '60s optimism that feels honest, not arch. And the minimal piano-set-to-metronome-beat"I Could Be the One" is kept aloft by Lewis's charmingly breathy vocals. She occasionally overreaches, as on the quasi-industrial"Beauty and Wonder" (try as she might, this lady just can't sound threatening) and the funned-up"Love Him." But Lewis has her ABBA/Kate niche all staked out and finely feathered, so it's easy to forgive her for a couple of indiscretions.
