cat.flp performing at Goop Week #7, as recorded off of a Twitch stream when it aired on 6/26/2022 by my friend. This is a normal Type I cassette, recorded on some old Teac machine. There is a verbatim airing of a Shoebill song about halfway in. This should be basically identical to this over here --    • CAT.FLP @ GOOP WEEK 7 | JUNE 26TH, 2022
