I think general rule for application is, that you have to apply at least half, if not two thirds more than you need. If you need 5000 euro, you need to apply for 10K at least. At least that is what was told to me by others who do it. It is likely many institutions give you some money, but not all. So one got to pretend as if you need sum X, so when you get half, that'll cover entire thing.
I've been told story about art music fest in northern finland. Bringing over lead vocalist for orchestra, could be matter of tens of thousands of euros. Out of the huge budget, couple thousands was handed to electronic music, and they could manage entire line-up of international performers and have actually good audience for it, while the costly classic singers would get less interest. This kind of thing will not shift the approach. There is certain values for what art is funded and what is not.
Most of the time, underground music is self sustainable, or everybody are ready to lose a bit. Classical music, opera, ballet, museums, and so on, are purely depending on funding.
It is curious, that I think there is also different set of mentality in 2020, than there formerly was. When living in times when crowdfunding or requests for support is quite frequent, I am little cautious. Of course, it ain't the same as getting money from institutions.
I get idea of for example podcasts. Guys spending hours and hours of time and their money to do artists and listener favors. While possibly liking what they do, it may be still a bit different thing than spending that time on own art etc. I feel functional way to pay for such thing is good. That said, I have yet to even first time look into this patreon site.. I know it'll be some sort of yet another new account to create and... I have utmost passion for noise, but nearly irrational hate for logging in into yet another system or site.
I dislike when the demand for funding extends into projects where it really would not be needed. Certain types of artists who have fundraising just for sake of... maybe merely because it is possible. For example, I do not think releases should be generally bought because of support. There should be other reasons.
In some circles it is considered normal, that you will ask handouts for all things, and do it if someone pays. Recently listened some artists interview where he would tell the typical routine that he had dozens on projects that could be done.. and those that get funding, get done. If there is no funding, idea is rejected. While in old school underground, I don't think handouts were considered anything to admire, and you did what you needed to do.
(As example, needs of noise shows are quite low budget, unless you'd have to pay plane tickets and such. I think video projectors suitable for noise gigs, do not cost almost anything at 2nd hand market. 100e should get you good one. Most have possibility to buying small plug as addition to older cable, so you'll have lightning or mini usb in, to play videos from phone etc. I would not be surprised if some noise guys have the old projectors laying around, unused for years. You don't necessarily need big funding project, but ask around a bit, ask advice, check out what's out there, and of course 100e is a lot of money for some, but in theory, one day you'll have noise show where 10 guys paying tickets will pay it back... )
