Where abouts in this modern age would one go about finding such a thing?
Here? Some obvious website somewhere? Just walk around the streets hailing our request?
Midlands based, Burton but Birmingham or Derby would do, probably gonna end up sounding like a cross between Alice in Chains, Kyuss and Deftones.
don’t think there’s one good answer, just have to try your luck a bunch of places and see what comes back. most of those paid sites like bandmix etc are awful but a lot of people just put some contact info on their page so you don’t have to pay. try gumtree, put ads up in local rehearsal rooms, put an instrumental demo up on soundcloud, etc. good luck.
