Posted this in the pit, but didn't get a reply. As well all know, Christmas is quickly approaching. My parents want to know what to get me, and music wise I've gone for http://www.amazon.co.uk/gp/product/.../ref=sib_rdr_dp this book, and I'd also like a CD of backing tracks to jam to. Although it doesn't seem to be something that's easy to come across (although to be fair, I've only done a quick google search)

The only ones I've been able to find have been blues backing tracks, if you could find something for those with a harder inclination (metal, rock, although a mix of stuff would be fine as well), then that would be awesome!

There's also a backing track band on UG somewhere. That has multiple styles in there too, and their track list is growing, albeit slowly though.
