I am always involved in the negotiations of unreleased shows as I still keep doing my own research to find old bootleg and I can confirm, all the recordings that pop up lately has a price. It's very hard for me or some other two friends (who always help covering costs) to get it. NINLive and DeftonesLive both have a part where fans could contribute to help the site somehow.
What I mean... It's easy to everyone just sit here and request to release stuff when they have zero idea how hard it is to FIND about a show existence, then find the filmer/taper, then convince him/her on sharing or selling (mostly is money involved) and then make it happen... Sometimes stuff like that take 1-2-3 years.
Dragon Festival 2001 and Smoke Out festival 2003 both proshot. This is an example of two shows which cost more than 2.000 USD. It's not too easy to pay for this and just put it on YouTube if I had to do it alone. If it is a fan crowdfunding, that sound more fair releasing for everyone.
