Can I submit a band that is widely famous in the Brazilian scene whose only release I can find a real proof of its physical existence about is a 4-way split, but a their 20-minute demo is available in their official website?

The band has already been rejected because I should either present a proof of the demo's physical existence or it should be longer, but I hadn't presented this split.

Are you talking about Post Atomïc Dogs?

A split would certainly help matters, be it digital or physical. Do you have evidence for its release and availability?

I am.

I have two links for distros selling the physical release and a link on one of the bands' bandcamp, but the latter has one song missing.

Post them here, please.

EDIT: Oh, you already resubmitted. Works too.
