tbh i dont know or care, think logos and mumdance talk about it in their interviews someone posted one early in that thread where they explain, think its supposed to be a feeling u get from these abstract ones without normal beats, i used it as title cos it was what people were calling some of those styles i wanted discussion on- the weirdo mumdance/logos/rabit stuff although it’s not something i listen to/enjoy that much,
i used it also cos it seemed to describe some of the more ethereal synth stuff nicely (ie banshee, myth, forever forever, zomby), which is the stuff i prefer, though i think in that i was using it wrong
i dont know why people always assume that means it’s music without bass- that’s dumb af, mumdance and logos sets and tunes give subs serious work out
check what @nclpad posted ere Glassy/Weightless Grime might clear things up, haven’t personally checked it tho
