Slipknot in London

Slipknot are an American metal band formed in Des Moines, Iowa, in 1995. Their percussion-heavy sound, masked appearance and albums Slipknot and Iowa established the group’s identity; their best-known songs include “Wait and Bleed,” “Duality” and “Psychosocial.” Slipknot joined Ozzfest in 1999 and soon began touring internationally. Their 2002 performance at London Docklands Arena was filmed for the concert release Disasterpieces, and they later played arenas and festivals on the All Hope Is Gone World Tour. Slipknot perform as a masked full band centered on vocals, guitars, bass and drums, expanded by additional percussion, samples and turntables. Masks and coordinated stage clothing have remained central to the group’s concert presentation through successive lineup changes. They founded the recurring Knotfest event in 2012 and headlined Download Festival on multiple editions. Their festival history also included repeated appearances at Rock am Ring.
