Hi Newbee
Lets start with an easy one that everyone can do and it will help everyone see where we all are.
Beatles Abbey Road: Track 10 "the crickets"
This is one you can use in the studio, at home or even a pro event stereo mix. It's one of the most written about references as well as used in classrooms.
Most of the time you would have everyone listen and then write and draw what they heard. Then they hand it in to the teacher and the different versions are then discussed. I've done this as well on TuneLand.
