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!

Ex Output:
Negative

I used this program for my science class. My students loved it! They learned some interesting facts, saw damage from earthquakes we talked about in class and never once did I hear that it was boring! Can't beat that!

Ex Output:
Positive

Got this JUNK from the Thank You network. It failed even the assembly test - the thing is so badly manufactured that the connection to which the pressure hose connects on the body of the washer was completely misaligned. There was no way I could connect the nozzle. OK - I thought it happens. I tried to call their 1-800-521-8559 support number and was on hold for 42 Minutes both on the Customer Service and Sales lines and then they cut me off. I did not even talk to a human! Their website is a joke. This is a typical bottom of the barrel Chinese company trying to dump poorly built stuff on the consumer. DO NOT BUY this and encourage such companies that dont give a hoot about the customer.I'm returning this and telling every retailer to dump this.AM
