One I picked up cheap was Phil Collins final farewell tour. While I enjoy most songs as background music, the start of the disc can really show off the Axioms.
The track is called Drums, Drums and more Drums and is 8.5 minutes of Drums.. Starts off with Phil playing then another drummer comes in, they go back and forth, then play together and then a bongo(?) player comes out and they all play. This track is probably the loudest I've played my system and the Axioms really shin with the mid range and crispness. Just be sure to have the remote handy as when the crowd cheers out the rear speakers it does not sound the best.
