Help with idiot guitarist and grindcore

[Ampeg SVT]

Alright so my friend in my current band wants to branch off and do a grind thing. Now while I like grind stuff, this guy wants to tune to Eflat, A, Eflat, A, B flat, E.
When I read that I was like "you cant be serious", now I thought we would be tuning down.

No actually we are going to pretty start from E standard and tune strings in ways that make no sense whatsoever.

Then he texts me and tells me "Oh im going to use 5 strings instead of 6 so its the same but without the low Eflat"

&&%^&%^*%^*^&$*^&*^&*^

I told him most grind bands tune down but he says "only good grind bands like ****** tune up" I told him that was a stupid idea, he says "Grind bands are crazy so tuning up and removing the low string is one step to being crazy"

This guitarist is one step from making me go bonkers.

I want to play with this guy but how should I reason with him.

The main issue is that most kids around here cant play guitar and I only know two kids that are good, one is an egomaniac and the other (the one here) is just an idiot.

So what should I do?

Can you share which bands he references as good so we can get a frame for where his mind is on this reasoning?

Why would care how he tunes his guitar. You don't have to match his tuning. You can still play all 12 notes in standard tuning.

I only knew one guy who is in a grindcore band...the one track I heard was ridiculous noise...if you play in standard and he is in crazy tuning it'll probably sound better than that did.

Seriously I would get on Craigslist and start lookin around.

I play in a Band where I had a similar problem, keep to the tuning that you want and play from that, with the "-core" kind of music sometimes the different tunings actually makes the music a bit more interesting. My Guitarist plays C tuning and B Tuning and i had one bass so i said screw this and got a 5 string, i play standard B the whole time and not a problem and when he is in C i just make my own adaptions to fit B, Key to this story... bass players know best :P Say you have taken his "style" into consideration and play how you want, its your low end not his!

Play your bass, and let him do his thing. If the end result is crap, address it then like "the compositions aren't coming together, and here are some ideas for how we can improve them." Otherwise just view it as another creative challenge or dimension for your own development.

Oh, that's pretty simple. Tell him that he can tune however the heck he wants, if he gives you standard notation of everything he writes in alternate tunings.

I tried reasoning with him, wasnt very successful...

Ive jammed with him before outside of our current band, he is a good guitarist, its just I had to draw a line.

Craigslist here I come.

You are just going off in different directions - that's fine, but I can't see how using different tunings makes someone an idiot. People have been doing that for decades, some people like a more experimental approach and others don't. No big deal.

[OtterOnBass]

The only question you should concern yourself with is how good does he sound. People with different approaches that fail are idiots, people with different approaches that succeed are musical geniuses.
