Dang, is there some obscure world that you haven't at least glimpsed into? I looked into Olympic Carillon a bit since I hadn't heard of them before. Usually when talking about carillons one talks about the foundry that made the bells--which OC doesn't do. But still, the rest of the parts of building a carillon that aren't about casting tons of metal are also extremely important to the overall character of an instrument like that. Things like positioning of the treble bells, for example, which are several orders of magnitude (!) smaller than the largest bass bells, can have a large effect on how the instrument sounds to folks listening on the ground. Before this trip, I'll have played carillons with bells cast by Gillett and Johnston, Taylor, and Paccard. After this trip, I'll be adding Hemony, Eijsbouts, de Haze, and Petit & Fritsen, with the oldest bells being Hemony bells from 1651! edit: Holy shit Olympic Carillon did a renovation of the carillon at Riverside Church in New York City. Riverside's carillon has the heaviest tuned bell in the world as its bourdon (nearly 41,000 lbs)
