Concerning the band Marnost from the Czech Republic: They say on their official website they released their single on cassette, but it is also up for free download. Now, the problem is, it is impossible to find any distro that has this release, so the only "proof of existence" is what the band said.

Is this one too close to call?

They said they released it on a cassette, what more do you want? You can ask them for a picture or even try to buy one ...

Here you have even a tape layout:

Well, I tried to add a band a few months ago, but the only proof of existence was also via the band, and that band got rejected because there wasen't enough proof they had released something (only had a cd layout).

So, I just wanted to check out how far the proof of existence rule goes.

I have sent them a mail and asked them for a tape, because I want to cover it on my magazine. I will let know know once I get an answer.

Alright, thx.
