UMUR "Erosive Offals (Malignant Necrotomy)" is the first demo recording by Swedish goregrind act General Surgery. The demo was independently released in March 1990 and it´s the first of three demos which General Surgery recorded and released during 1990. General Surgery formed in 1988 as a tribute to the early Carcass releases and it was always a side-project for the involved parties, who also worked with contemporary artists like Afflicted/Afflicted Convulsion, Dismember, Carnage, Unanimated, and Carbonized.

So with that premise laid out, it´s no surprise that the three tracks on the 5:51 minutes long demo are brutal, filthy, and gore themed grindcore with some deep slimy growling vocals complimented by higher pitched snarling vocals. General Surgery hit the balance right in terms of paying tribute to Carcass but also bringing just a little bit of themselves to the table. Thankfully "Erosive Offals (Malignant Necrotomy)" is not one long blast beat fest, and General Surgery actually quite often take the pace down to a heavy mid-paced groove.

Considering that "Erosive Offals (Malignant Necrotomy)" is a goregrind from early 1990 it´s pretty well produced. it´s of course noisy, unpolished, and raw sounding, but that´s how this type of music should be experienced. A 2.5 - 3 star (55%) rating is warranted.
