Want to do school's talent show. Recommendations?

[waylay00]

OK, I'm wanting to do my school's talent show using a backing track and doing an instrumental performance. I'd prefer it to be something hard rock/blues rock (not necessarily a strict I-IV-V). Something along the UFO, Deep Purple, Gary Moore vein. Does anyone have any instrumental song suggestions or backing tracks that might fit the bill?

Are you dead set on using a backing track? I've done many solo shows and always love trying to make a song that's usually filled with lots of sound work on the guitar alone.

If you want to do an original (but influenced by type), you could always use one of the Signature Licks accompany CDs.
