@B 24 EDO is the most common alternate tuning system used by western composers. It's a lot more intuitive to learn because it keeps all the existing musical relationships in tact, but it's also less interesting for the same reason. I do like the jazzy stuff worth checking out this track:

I've also used quarter tones in my own writing this is from "Woodworks" and "Simple Sabotage Field Manual" respectively. Notated differently. Notice they're only ever used as passing tones, not a significant part of the harmonic language, although I did want the flute in woodworks to be a quarter tone flat.
@owen Ah, yes, Ludemann! You turned me on to him a while ago and I have a couple of albums of his. Great stuff.
@B Some interesting stuff I haven't heard before in there. Loved the color of that really high EDO piano doing all that chromatic stuff with the orchestra. That dutch oregon was ugly as hell
@owen Quarter-tone pianos! Never heard of such a thing.
