A parabolic microphone is good for picking up things like people
talking from a fair distance. I use to use one when going to press
conferences etc as you could stay back out of the crowd and still get
a good recording. I also used one when providing a transcription
service for things like arbitration hearings as I could sit at the
back of the room and point the mic at whoever was talking and get a
good high quality recording from a reasonable distance. 

I doubt if it would be very good for things like usic as the parabolic
reflection of the sound waves into the microphone is probably going to
cause all sorts of weird phase shifts and frequency distortions.
