Extreme Noise Terror (often abbreviated to ENT) are a crust punk and extreme metal band originally from Ipswich, England. Formed in January 1985, they are one of the key early UK grindcore bands and are still together today. Notable for their use of dual vocalists and for recording a number of sessions for BBC Radio 1 DJ John Peel, Extreme Noise Terror initially started as a hardcore punk band. It became quickly evident from early shows that they were far more extreme than many bands of that genre. Together with Napalm Death, ENT helped characterise the early, archetypal grindcore sound: Fiercely political lyrics, grinding guitars, extremely fast tempo and often very short songs. In 1992 Extreme Noise Terror appeared live with dance music group The KLF at the BRIT Awards. They also worked on The KLF's abandoned album The Black Room.
