Extreme Noise Terror, once a praised crust punk/grindcore band, now known as a death metal/grindcore band, are from Ipswich, England. Formed in 1985, they are one of the key early UK grindcore bands and are still together today with vocalist Dean Jones as the only original member.

Notable for their use of dual vocalists and for recording a number of sessions for BBC Radio 1 DJ John peel, Extreme Noise Terror (often abbreviated to ENT) 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.
