HellHammer hail from Switzerland and should need no introduction, but if you insist, they are the band that existed prior to CelticFrost. They are an intricate part in the birth of black metal. technically Hellhammer only officially released(while they were a band) one 12" E.P. and this is it the 1984 release 'Apocalyptic Raids'. There is a beauty to their LO-Fi sensibility, creating a raw and anxious feeling, making bands like this far more scary then most other Extreme Metal bands. HellHammer also does a nice job of incorporating some different styles to their music like the very slowed down doomy/Sabbath inspired track like 'Triumph of Death'. Its arguable that this could even be a Punk rock record just based on the sheer rawness of the album. I would have to say, the best way to describe HellHammer's sound would be if Venom(Welcome to Hell) and MotorHead(OverKill) had a baby and raised it on BlackSabbath .. Its Raw and dark with driving beats, what more could you want?. Plus Tom Warrior is a big time Amateur Rocket Enthusiast, thats right he builds rockets in his garage, and sets them off in the park and if you look very closely you will see him wearing NASA t-shirts in a lot of photos of him off stage.
