Bluesman Seth Walker sings like a man who's had his heart broken one too many times. Since his genre of choice calls for a bit of misfortune, that's not necessarily a bad thing. It doesn't hurt to listen to his songs if you're going through a breakup — or wish you were. This Austin, Texas-based singer has a knack for pouring subtle emotion into his compositions and letting imagination take over in the listener's head. That's an important songwriting gift in itself, and if you appreciate a good blues musician who can make you forget about your troubles, then it would be a good idea to check out Seth Walker while he's in town. You may have seen him with Johnny Winter at the Culture Room last year, and he's back again for a small tour of Florida. This weekend, he'll be in Boca Raton playing his own brand of boogie-woogie blues.
