Alice in chains song intro in Doom2?

So I was listening to some good ol' Alice in Chains. I realized that the song "Them Bones"'s intro seems to resemble Doom2' "Barrels O' Fun" Map.

Anyone else see (or hear, rather) the resemblance?

Indeed, and these influences are pretty well documented by now. See, for example: audio comparisons or the wiki entries for Doom music and Doom II music.

Ok, thanks for that info.
