Vulcan's Dark Master serie is pretty unique.
First off, these cymbals are not very thick. Actually, you can bend them with your bare hands if you want to.
Second, their surface is raw which usually makes cymbals more controlled and dry.
Therefore, the ride cymbals from this series sound quite different, but in the best possible way!
This cymbal har a light feel and a pretty good control. The stick definition is medium-light with a slight "wash" beneath. If you crash this cymbal, you awaken the dark sides of its tonal register.
And finally, the otherwise raw surface is actually not completely raw. Vulcan has polished it so that it almost shines (it may be difficult to see on photos).
All in all a lovely, light, and controlled ride with lots of possibilities.
