Here's Avant-Garde music Wikipedia page (no mention of lo-fi) Avant-garde music

And here's Lo-fi : Lo-fi music
I would suggest putting lo-fi into the Rock section. Also, I didn't realize this compilation is for popular genres only, for now. Then Avant-Garde section basically represents those explorations that had a big influence on popular music. So, minimalism and experimental music are fitting. I would also suggest Drone and Noise for the Avant-Garde sub genres.
