Too many people get their hands on pedal steel guitars and lumberjack shirts and start thinking they’re Glen Campbell. That’s never been a problem with Chuck Prophet, the San Francisco singer-songwriter and former Green on Red member who has spent 15 years fighting to make Americana music sound (a) good and (b) listenable. It’s not as easy as it sounds. Just look at Jay Farrar. But on his seventh and latest solo album, Prophet delivers a set of ace tunes like “Smallest Man in the World” and “West Memphis Moon” simply by clamping his hard-luck voice on dreamy, soft-focus melodies that aren’t afraid to stretch expectations. And not one of the lot sounds anything like “Rhinestone Cowboy”.
