Napalm Death is an example of a band that I didn't like until the shitty music of the 90's and first half of this decade tanked the bar so far that I consider anything with a chord change to be genius.
I didn't listen to much grindcore, but the first few Carcass albums ruined everything else for me. Napalm Death wasn't quite as good as "Symphonies of Sickness". Carcass sucks now, did Napalm Death get better?
The clip you posted was the studio version of the song, dubbed over an Imovie collage. Those never fare well here, even with songs long enough that the Imovie clip would actually take time to make.
