Black Bong is great but I like Nise Kyûseishu Domo even more.

why would I be scared of a man with a pho hawk and a perfectly lined up gotee ????

Dude, don't underestimate stock art models.

He's not even holding the gun sideways which as I understand is a kill shot. Anyways:

Black Sabbath- never gets old. Plus you have Ozzy and Dio.
Judas Priest- classic after classic.
Iron Maiden

Easy choices

Black Sabbath: I know everyone's choosing them, but they just have such a diverse discography that they'd never get old.

Bathory: From my favorite form of extreme metal (primitive 80s black metal) to their epic Viking metal, this band has two of my all time fav metal sounds.

Manowar: Need my fun.

I need to listen to more metal. I could very easily live without metal at the moment. That means I'm slacking.

Agalloch
Cult of Luna
Dillinger Escape Plan

Devildriver
metallica
incubus for the lighter sunnier days

Sigh: My favourite band, they've got a great amount of variety in their discography and could pretty much always satisfy my Avant-garde Metal itch.

Blind Guardian: Another favourite of course, and would do the job of satisfying my need for melodic/harmonious/consonant Metal in that they're Power Metal, and excellent Power Metal at that with their own decent amount of variety.

Necrophagia: These guys wouldn't always be in my top three, but I've been liking them a lot recently, and I feel they would satisfy my need for Extreme Metal pretty well for a while, though I don't think they could really make up for the lack of many dozens of other Extreme Metal bands, I feel each of those other bands couldn't do much better on their own in satisfying my taste due to none of them really encompassing all of what I look for in extreme metal either, and none of which I would consider "the definitive" Extreme Metal band, so Necrophagia would do just as well as all of the other ones individually. Anyways, I think Necrophagia would be good for their really awesome mid-80's demos, their first two classic 80's Proto-Death Metal albums, their groovier work for varieties sake, those three great EPs they released in the early-mid 00's, the more brutal 2011 release they did, and their most recent, very solid release. Also, that many of those releases have different feels to them, and all of their work tends to have quite interesting, somewhat unique atmospheres which focuses on cool Horror Movie/Occult themes often very well, which has made them one of my favourite Death Metal bands.

Considering the premise, I've come to decide that I could live without metal really. I mean, I listen to a lot of it these days, but there are so many other genres out there that wiping out one (although it is a VERY large umbrella) wouldn't be too bad. I can find what I look for in metal in other places. I think the same can be said for other genres as well. I think the only genre that would be hard for me to part with apart from three artists would be avant-garde music, but that would depend on how strict the definitions were. If it were an affront to anything with an avant-garde element it would wreck me, but if it were against straight up avant-garde artists who you couldn't call anything else, I'd be set. They'd catch me listening to Beefheart one day and I'd tell them to go **** themselves because they didn't ban the blues (although I would probably pick him just to be safe).

That kind of goes for metal as well, how strict are we with this? Would I be allowed to listen to something like Death Grips or Peter Brotzmann, who have a lot of metal elements/influences, or would I be shot on sight?
