prefferably for voice, piano, or Tenor sax. But anything would be appreciated!

If you can transcribe from guitar tab I wauld recomend going to ultimate_guitar.com If you need sheet music i would go to an apocolyptica fan site they should proboly have sheet music
for cello that could be used to transcribe Im trying to do the same thing with my trombone

for a tenor sax? Thats AWESOME!!!!!!!!!!!!!! I play an alto. If you find any for that while you're at it, let me know.
