this mixtape was made around 2016-ish.. before the first SDEM tapes and CPU 12" .. it was intended for release on cassette, but for reasons now unclear (?) it got shelved and then somehow it was forgot about..
however it had been sent to philip washington aka cygnus (cygnusat.bandcamp.com) , who had not forgotten about it and had infact surreptitiously passed it to autechre..
some years passed..
Then during 2020 UK CoronaVirus Lockdown 1, AE did a 2 week long DJ session / stream on mixlr, where this mix was played in full.
That reminded me it existed, and i recovered the files off an old hard drive ... and now you can listen to it again here, or buy a download of it if you want.
As the mix preceeds the CPU / Opal Tapes / Seagrave SDEM releases theres a bit of crosstalk : it includes a different version of BX16 which was on the CPU 12 shop.cpurecords.net/album/index-hole (maybe BX12 or 13?)
