COLOMBIAN DEATH METAL!
Going through a few I haven't yet heard, aside from the masters like Goretrade, Internal Suffering, Ancient Necropsy, Amputated Genitals, and the others I forgot.
Suppuration up first with their album, the aptly titled Pain And Suffering. Very tinny yet well-toned guitar production, drums overpower everything, especially the bouncy snare, but I don't mind much. Some epic riffs appear (similar to Ancient Necropsy but with less tapping or sliding), and the vocals of course rule. There is even a litttttttle bit of acoustic guitar!
