so lemme get this straight.
the artist supplies the music, as well as the scratch to make the release for your label. then you presumably sell it based on trust, and again pay the artist based on trust after the product that they paid to have made has been sold, after you take your commission. what happens if noone buys the tapes or if you cant sell them? have you ever worked with a label before, do you have any credentials of any type to sort of prove to people that you can be trusted? any transactions with members here or anything like that? i ask this because you're asking for people to contribute to you with no risk to yourself and a possible reward to others who work to potentially build your label's releases so i feel like this is a valid question to ask. you also say you dont intend to make any cash from it, but that you will take a commission. all in all, it doesnt sound like a very solid pitch to go about starting a label.
It's a bit tough to take in what you're saying when it doesn't seem like you've taken much time to write it out properly, but I will do my best.
I have been on the forum for years, was a mod at 8bc, and have plenty of interaction with members. Either way, it would be based on trust - much like a lot of things in the DIY community. TBH though, if you want extensive references of my musical experience before spending about £10 to release 5 cassette tapes, then you're kind of missing the point, and it isn't the sort of release that I'd be interested in doing anyway.
This is something I am doing purely for the love of it. I know plenty of artists who record their own music and would love a physical release but don't have the time, equipment, or inclination to do it themselves. In that case, I can do it for the cost of materials, plus a small commission if they sell - which isn't unreasonable given the amount of time and work that goes into the production. The quantity of releases and runs involved would be so small that there is no prospect of making any cash. In other words, this isn't a money making exercise. It's a DIY, home label, not some commercial venture that I am pitching.
For me it's more of a collaboration with like minded folk. If it doesn't work for you, that's cool.
