The Meinl 19" Byzance Extra Dry Thin Crash Cymbal is dark and earthy, giving you a low-pitched, kinda trashy tone that is deeper than you would expect for its size. It's particularly effective at low volumes, when you want something very tasty to accentuate intricate playing.
At 19" in diameter, this cymbal could almost be a ride, and you can treat it much like a crash/ride to give yourself one extra color option on your drum set.
Byzance Extra Dry cymbals are unlathed on top to keep sustain very short, with the added bonus of a very cool raw, dark look. Extensive hand hammering creates a complex wash of overtones.
The very thin profile of this cymbal gives it the ability to max out on its upper overtones without putting much energy into hitting it - even a soft blow will activate the full bloom of the instrument.
