What is a carillon? Only one of the most metal instruments ever created (heh)! They're comprised of at least 23 tuned bells, and played via a console that looks like an oversize piano made of levers.

If people are interested, I can post more recordings of this instrument and put together a little something introducing these sonorous beauties:
