I own all of Amy Grant's other CD's and this is the worst! This album is so depressing, it makes sense when you realize that her marriage was on the rocks at the time. I find it amusing that she puts out one of her worst albums ever and her ex-husband (Gary Chapman) puts out one of his best. It seems like she is trying to break out of the "Gospel & Pop" mold that made her. I bet she does country (with Vince Gill) next.

As a musician and musicology student, I am very familar with both the "classical" world of music, and the popular world of music, and I have to say that perhaps string quartet versions of R.E.M. might be interesting, but you need a creative and enterprising quartet (such as Kronos Quartet, etc.) to do this. This CD is greatly disappointing because the transcriptions are simplistic and lacking imagination. String quartet recordings can be very exciting, but not here!

Negative

I've read several Bayer novels and enjoyed them very much. After hearing that this novel won an Edgar award I was eager to read it. Well...that must have been a very thin year for Edgar nominees. This book was a severe letdown. Totally unbelievable and it got sillier and more ridiculous the more pages I read. Honestly, I can't believe Bayer would even want this one still in print. His other novels, and the ones he has written as David Hunt, are very good. But this one reads like the work of an amateur by comparison. Give it a miss.
