One of the more spectacular attractions at the Colorado Renaissance Festival is Cast in Bronze. The instrument you see there is a carillon. It is comprised of about 80 bronze bells and is played with pedals and a keyboard that has to be hammered with bare hands. Very few exist in the world. Also, it weighs several tons, which makes it hard to transport. Nevertheless, one man has managed to arrange well known pieces such as "O Fortuna" and "Carol of the Bells" to include this incredible instrument. Well worth taking time to listen to
