Zildjian 18″ K Cluster Crash Cymbal

From Zildjian:

Expanding on the Zildjian K line, and exploring new trashy, alterative sounds, the K Cluster Crashes fills your special effects needs without the holes. Characterized by distinct cluster hammer marks and a distinct dirty sound. The K Cluster Crashes are extra thin in weight with an unlathed bell and feature the traditional K style hammering technique with additional cluster hammer marks that create a darker, trashier sound with a fast attack and great response.
