Through a seven year history, Clagg have endured enormous challenges to emerge as one of Australia's leading doom and sludge bands. Building their sound upon a foundry of monstrous guitar riffs, a bludgeoning rhythm section and demonic vocals, Clagg have been persistent in spreading their evil word amid many setbacks. Following multiple line-up changes, Clagg are now at their most cohesive and crushing.
Just some nice guys making nice.
