[EX Q]: This band has a straight forward approach to music that is sturdy, simple, aggressive and a little annoying, in a good way. The often frenetic lead guitar is right up front to create a classic rustic American sound. This band must like Blind Willie McTell as they cover Dying Crapshooters Blues and mention Mctell in their original track Down at Danny's. If you are looking for something different with a classic American roots music sound - this is a nice find.
[EX A]: Positive

[EX Q]: Product reviews are very subjective. Based on the reviews of this boot I hoped for a great boot at a fair price. Instead I found the boot to be subpar in terms of comfort. They shoes were stiff and far too 'roomy'. My feet where floating inside them. I returned them immediately. I've had far more comfortable boots right out of the box.
[EX A]: Negative
