The D-ROCK is a bi-tonal hybrid cymbal that is dark, versatile and controllable.

Sonic contrast develops as the major part of the bow and bell is deeply hammered, tightly lathed and left with a dark finish. The edge of the cymbal receives the equivalent lathing and hammering, yet finished to a brilliant sheen. The underside of the cymbal fully receives the same lathing and hammering and is left completely dark.

The crashes are complex or may be referred to as having a darker bite.
