Since I began teaching last year I've been resurrecting these sorts of books I bought when I was a kid; practicing scores and pieces I could of only dreamed about playing (while attempting to master Killer Instinct on the N64).
You can tell these books are old...just look at how the cover page for the book of Beethoven's sonatas is ripped from its source!
Now I can't stop practicing these damn things and they're getting in the way of my Japanese studies!
