Sore Throat formed in Huddersfield, England in 1987, becoming one of the earliest and most extreme proponents of noisecore — a subgenre of grindcore defined by total sonic disintegration, ultra-short song lengths, and confrontational anti-music aesthetics. Their debut Unhindered by Talent (1988) and the 101-track Disgrace to the Corpse of Sid demonstrated a commitment to extreme volume and brevity that would anticipate the most violent edges of grindcore. Active until 1990, with a brief 1991 reunion, the band influenced the British underground disproportionate to their short lifespan. A new EP, Starving Wolves Stand & Fight!, arrived in 2022 on Bandcamp.
