London deathgrinders Gorerotted formed in 1997, inspired by horror films and subjects such as death and mutilation, with song titles such as 'Only Tools and Corpses' and Masticated by the Spasticated'...lovely.
Musically, they employ dual vocals, a deep growl balanced by high-pitched screams, drop tunings and blast beats. Too amusing to be offensive, but still not one to take mum to.
