Actually my interest in microtonality comes from performances, rather than any theoretical writings, including Ligetti even though he didn't score it in his Lux Aeterna or Lontano or Atmospheres (using his so-called micropolyphony instead) - but on hearing the performances one definitely detects microtonality. It is impossible to perform these pieces without becoming microtonal. The musicians cannot hold the pitches.
But also, I love out-of-tune ensembles. I have heard some sounds beyond anything normal from them and want to incorporate this into deliberately composed pieces. I've noticed how much I enjoyed de-tuning the tempered perfection of samples, but also how a triad that is detuned is a new musical entity. This of course is nothing new in theory, but hearing it in this context is very interesting.
