Southern political personalities, like sweet corn, travel badly. They lose flavor with every hundred yards away from the patch. By the time they reach New York, they are like Golden Bantam that has been trucked up from Texas - stale and unprofitable. The consumer forgets that the corn tastes different where it grows.

A Deap Vally renaissance is going to begin next year and will be our focus for the start of 2013. They will blow the cobwebs off a music scene that has become just a little bit stale.
