BOC Maxima (cassette) / (99.82% CDDA): FLAC
Here's how this particular recording became available:
Boards of Canada gave this cassette to Autechre,
Autechre gave a CDR of a recording of the cassette to Richard Devine (Schematic),
Richard Devine gave a copy of the CDR to Alex Graham (Lexaunculpt),
Alex Graham gave a copy of the CDR to me,
I gave a copy of the CDR to Jonathan Canupp (Ten And Tracer),
Jon Cannupp gave a rip the CDR to the general public via followers of the old IDM ring.
This 16bit recording of a cassette is the best rip we have.
All lossy rips I've ever found are sourced from it.
We are not meant to have this music.
BoC has not given it to us.
We can only covet it.
It is not ours.
For years, I felt that I would pay extortion prices for a rip of the CD.
But I realized I could only accept it as a gift for it to become mine.
