So the EP is out there: https://www.qobuz.com/nz-en/album/ill-remember-madonna/txq68glxva0sc
The volume is uneven, so the vinyl mixes may be more recent transfers (LAP has the same particularity). I think the volume boost also enhances the hiss.
I think those were bertrand's rips of the 2001 CDRs, but I don't think the IR mixes were ever found on a CD.
Hopefully they get their stuff together for the release or it would be a huge miss.
I'd rather use the file from the original 'Madonna' release on streaming, that's the proper master for the 12'' version. I think they replaced it with the remastered version now, but maybe someone still has a copy?
