[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]: I was expecting to read a book about the Amish. What I read instead was a very self centered book about a woman searching, rather blindly, I felt, for herself.She had very little in the way of insight into Amish life, even after spending a period of time with them. And her inability to get outside of her own head/her own life was not terribly interesting to read.For someone who always longed to be a 'star,' I am sure publishing a book was quite a thrill for her. Shame she used the Amish as a platform for her own ego.
[EX A]: Negative

[EX Q]: There are serious inaccuracies in this book that can cause a great deal of stress for a celiac. The section on medications with gluten is especially troubling as it causes someone who thought they were safe to worry for no reason. Most troubling is her treatment of the risks of cancer. Her treatment is both superficial, incaccurate and unrealistic. First she says that the risk is the same whether you maintain a gluten free diet or not. Then she says that the only thing you can do about it is to not worry about it. Her discussion of picking food out of a sandwiches is poor advice. In one section she understands the problems of cross contamination, yet doesn't seem to understand that picking apart food is more of a risk than using a toaster. Finally, her flip advice about how to avoid answering questions is ridiculous. Why not be honest instead of avoiding the questions. It's up to the person as to how many details they want to give. But avoiding the issue is not the answer.
[EX A]:
Negative
