From the BIAB Forum:

Matt Finlay made a demo, this is one of his existing BB songs, that he just played using RealDrums. It uses some shots (for the ending for example, Matt uses a shot instead of the typical ending). Anyway, you can hear the RealDrums here, and we are making a page with a number of demos, should be ready by tomorrow.
