Klank, also stylized as kLaNk or KLANK, is an American industrial metal and groove metal band that originated out of Long Island, New York in December 1993. The project began after Daren Diolosa, the brainchild of Klank, departed from the fellow industrial band Circle of Dust. Diolosa carried the project as a solo project until around 1997, when he began performing live. Following the live performances, Pat Servideo joined as a full-time member, with Diolosa and Servideo joining as a team. The band would go through many members, eventually settling on the lineup of Diolosa, Servideo, and former Every Day Life drummer Eric Wilkins.
