This one is a pretty good extreme METAL band from Liverpool, England. CARCASS. Genre: Grindcore (early circa); Melodic/Brutal Death Metal (later).
For those who don't know, Carcass is considered to be the major inspiration and musical foundation for most deathgrind/goregrind bands, as well as being one of the founding *fathers of melodic death metal *when they had switched their genre to the melodic death metal sound by the early '90s.
Pretty Heavy and Brutal 'Head banging' sound ! This band is very unique. The musicianship is also excellent.
