Even though I've heard these demos before on soundcloud, I've decided to post these here, in case some may not have heard them.

1) Style demos: https://www.youtube.com/watch?v=AEoZ1c_kVA8

2) Instrument solo demos: https://www.youtube.com/watch?v=__i24qX_FCA

3) Music demos: https://www.youtube.com/watch?v=yRQz8CrRn9w

Enjoy!
