And I forgot about nintendocore and bands like Error 37, Hanni Kohl, I Shot The Duck Hunt Dog, Mario Killed Pikachu, ... really absurd, but good

Fu Manchu (especially the earlier era), Sleep, Sword, Eyehategod, Acid Bath, Earth (Earth 2)

When I fell like it, I listen to Hijokaidan or Hanatarash a bit.

Also Research Reactor Corporation has some "nice" songs.

And last but not least, My Bloody Valentine and entire album Loveless

Reminds me, that I want to "fix" my install.

Ah yes, anytime I am making a script in bash and have to use something I have never seen before.
