Bonus post today, thanks to Angelo Bertini! He told me what to do and got this RHCP show digitized. No known lineage, but it has an odd printed tape label which makes me wonder if it was a bootleg being sold at record shows. It has that look.
Not too bad of a recording, probably a Sony D3 or equivalent.
If YOU want to tell me what to do, check out the patreon at the link below.
