Hard to pick just five , but my first and all time favorite is Opeth!
But at this moment that I'm typing this, here goes the top few :
Opeth, Death, The black dahila murder, Morbid angel, Hate eternal, Skepticism, Pointed mutation, Ekwon, Sargas, Chaos decent, Eternal candle, 5grs. Oh sorry I mentioned more but they're worth it !
