Unfinished as I still have to catch up on more recent years. Also all of the places on the list are of course subject to change as I discover more music from each year.

My taste is very much centred around the power of the riff. That means most of the albums on this list are thrash, death, heavy, black, or some offshoot of those genres.

1.After The Burial - Dig Deep

2.Behemoth - The Satanist

3.Carcass - Surgical Steel

4.Cattle Decapitation - Monolith Of Inhumanity

5.Fleshgod Apocalypse - Agony
