Check this out. There are some vids on youtube of people using Lamb Of God's Sacrament - Producer Edition and replacing drums and guitar parts with their own playing! I'll throw more vids relating to the producer edition as I find them, but this is a great starting point.
Just occurring to me when watching these is that you can use the tracks to practice your recording techniques. For example, you can work on your drum recording and mixing techniques in your home studio by re-recording the drums to the songs!
SWEET! Check these out!
