if you are into primitive industrial / low fi dilletantism, you’ll find some very interesting ex yugoslav wierdness on this great blog, with great essays about each featured project. no synthpop stuff though:

if you like cheesy polyphonic synth pop like denis denis, maybe you’d also like romantične boje from niš.
the problem with ex yu electronic music is that it always relayed too much on fucking CHORDS, and rarely used monophonic melodies. that’s why ‘beograd’ really stand out in my opinion.
a holy grail of low fi home made minimal would be ‘monotonik’ tape, self-released [and even reviewed in student’s press] in zagreb around 81/82, and ‘crna izdrkotina’ from vojvodina [although i’m not sure about this second name].
