This tape is not BoC, imo.
I think that this tape, when compared with the past dubious tunes that surfaced on youtube/vocaroo/etc, is more refined.
BUT, the proof that I search for when listening to unknown tunes is..the drums.
BoC have a particular way to work on drum tracks: they layer different tracks, some are live drums played by Mike, some are drum loops (some are probably sampled with the S1000 and then downsampled to lower bitrate), they pan different tracks L and R, put some percussions here and there, etc. The thing is, drums sound so full in their tracks. This is not a simple task, this must take a looot of time to get a perfect sound like that.
All these unknown tapes just use a single drum track at the center or at most two, one panned left and one panned right.
In my opinion their synth sounds are easier to get, you can use hardware synths or work with VSTs, use tape to add grit, make layers, sure a lot of work is needed here too, but the drums..well, this is something completely different.
Just my two cents
