Q: 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!

A: Negative
****
Q: Product was defective from day on and lasted a whole 32 days and now will inflate but by the middle of the night you sleeping on the carpet.

A: Negative
****
Q: Similar in style and tone (and usefulness) to Strunk & White's classic "Elements of Style". Short, pithy, intelligent. Lots of examples, followed by Professor Lasch's thoughtful, penetrating, often witty comments. Recommended for all undergrads.

A:
Positive
