Miscellaneous Old School Death Metal Classics [Part 1]
Entombed - Left Hand Path (Earache, 1990) - Entombed's debut is an undeniable classic of the genre, and is probably the definitive Swedish death metal album. Detuned buzzsaw guitar excellence.
Monstrosity - Millenium (Conquest, 1996) - This Florida band's second album, produced by the legendary Scott Burns, was the last to feature Cannibal Corpse singer George 'Corpsegrinder' Fisher. It's technical, but not too technical; brutal, but not too abrasive; some of their finest work.
Incubus (aka Opprobrium) - Beyond the Unknown (Nuclear Blast, 1990) - Incubus hail from Louisiana, and this was their second album. It was also their last, before taking a ten year break and then returning as Opprobrium (in order to avoid any confusion with Incubus the rock band). Brutal, thrashy, Christian death metal.
Fleshcrawl - Descend Into the Absurd (Black Mark, 1992) - The debut full-length from Germany's Fleshcrawl is essential listening. Death metal with doomy sections here, and also some hints of black metal. 1994's Impurity and 1996's Bloodsoul are also well worth checking.
