A lot of people here seem to be under the impression that grindcore was created to piss people off, to gross people out, and to be offensive.
That's possibly true.... but it was probably designed to piss people like
YOU off...
As Brenton has already pointed out, take a look at practically all of the pioneering grindcore bands (Napalm Death, ENT, Electro Hippies, DOOM, Heresy, Seige etc) before grind fused with death metal and mutated many times to become a trillion drum-machine based, gurgling, porn-obsessed bands of today.
They all adopted lyrical themes that were drawn more from
punk/hardcore music than
death-metal--
Anti-sexism, Anti-homophobic, Anti-consumer, Pro-animal rights.
In my opinion, AGONY were the closest band to
true grind of the whole night, both in music and ethos.
I am a huge fan of humour, satire, parody, and un-PC humour. I love playing in Cuntscrape/Maxi P (who I wouldn't call a strict grind bands by any means) so I totally get the humour of new types of grind. With some bands, unless you can read the lyric sheet, it's difficult to recognise the "humour" element--- that is assuming that there is one?
