Repudilation were one of the forefathers of slam death metal along with Devourment, but Repudilation are kinda overlooked. They didn't become as successful as Devourment but they also made some damn good music. The sound ain't very good on the album but it fits the music quite well. The guitars sound muddy and stay in the background, while the drums - which mostly alter between groovy and blast beats - are loud throughout the album, emphasizing the catchy beats' strength. And of course you have the obligatory guttural vocals which also add to the muddy sound. Check this out if you want some 'underground' sounding slam death.
