Guest list from Sverre of Audiopain

1. Kiss - Hotter Than Hell. This, alongside all other Kiss-albums from the 70's, had a huge impact on me. Hotter Than Hell is not my favorite Kiss album today, but I remember how this record in particular made me obsessed by the sound of the electric guitar, being only 5 years old or so at that time I already knew I wanted to play guitar.
2. Autopsy - Mental Funeral 
3. Metallica - Master of Puppets. Hard to choose which Metallica album that actually influenced me the most, but there is no doubt that Master Of Puppets had a huge influence on me at least.
4. Guns 'n' Roses - Appetite for Destruction. No further comment necessary.
5.  Slayer - Reign in Blood. Perfection...
6. Deicide - Deicide. The first death metal album I heard, I believe. It just blew my mind.
7. Darkthrone - A Blaze in the Northern Sky. Probably my first Black metal record. 
8. Mayhem - De Mysteriis Dom Sathanas (rough tape without vocals). Being fortunate to get hold of this a year or so before the actual release of the album was amazing. The drum sound was just so great.
9. Voivod - Dimension Hatross. Yes, I know, you all prefer "Killing..." or "Roar" or whatever.  But "Dimension" did it for me.  First.
10. Tool - Aenima. An art-ish approach to music.  So much dynamics going on.

Dark horses: Death Strike demo, Disneyland After Dark - Riskin' it All, Kreator - Pleasure to Kill, Alice Cooper - Raise Your Fist and Yell, Death - Leprosy, Burzum - Aske, Entombed - Clandestine, Kjøtt - compilation CD, Morbid Angel - Altars of Madness, W.A.S.P. - The Last Command, Aura Noir - Black Thrash Attack, Radiohead - OK Computer, Iron Maiden - Number Of The Beast
