Vomit Remnants - Supreme Entity (1999) + Indefensible Vehemence EP (2001)

From Japan, Vomit Remnants brought the proto-slams on Supreme Entity right around the same time as Devourment's Molesting the Decapitated. They're more obscure but just as gnarly -- pretty much the Pentagram to Devourment's Black Sabbath. (Although, to be clear, anyone who tries to tell you that Pentagram is as good or better than Sabbath is fucking wrong.) The Indefensible Vehemence EP is disgustingly brutal as well, and features what appears to be a tribute to Devourment.
