[EX Q]: I'm not a fan of the crime writing genre, so I require more than some blood and guts and a few nasty frights to make me speak highly of a crime novel. Unfortunately, I cannot speak highly of From Potter's Field.I know more about dogs than I do about forensic medicine, so it makes me suspicious of the novel's factual integrity when I read that a murderer's eyes are "as pale blue as a malamute's", when in fact (according to the Alaskan Malamute Club of America), a malamute's eyes MUST be brown, never blue.It also made me laugh to think that all the crime agencies (and the media!!) in the USA would be completely ignorant regarding the closest relatives of the country's highest profile serial killer. Although if the good guys had known some basic details about the killer's family tree, Dr Kay would have been left twiddling her thumbs, so I suppose I should quit complaining.Well, I read the book right through to the end, and it kept me amused, so I have to give it one star.
[EX A]: Negative

[EX Q]: If you are of a certain age and experience, you already know about Dharma Bums.If you are of another certain age and experience, this book goes against everything taught by Saint Ronald Reagan, and so you should avoid it.If you are young, give this book a try. Better yet, instead of buying it, go to the local library to read it. Unless the people I described in my second paragraph have taken over and there are only Approved Books in the library...if there are libraries at all. Libraries cost money, and that means (shudder) taxes.For everyone else: this is Kerouak's best work.
[EX A]: Positive

[EX Q]: "Motor City Moments" is Regina Carter's 4th CD and it is amazing to listen to. It opens with an uptempo, improvisational-like, number, "Don't Git Sassy" then settles into a contemplative, salsa tune "For Somoeone I Love," where Carter plucks her violin then make it laugh, weep and glide all in one song. I haven't heard the Milt Jackson version, but it would be interesting to hear the original to see how this interpretation is different. There also some interesting selections like "The Love Theme from Spartacus." Carter's lamenteous violin is softly accompanied by Marcus Belgrave's flugelhorn. In some instances, the two instruments merge into one sound. But the ultimate gem in this CD is Carter's version of Chattanooga Choo Choo. It should be a standard violin piece much like Mozart's Sonatas. It sounds like it was written for the violin and Carter is in absolute command here, with such fire and fluidity, I'm definetly impress! One should buy this CD just for this number alone.
