Nice input in here.
Although I personally think psychedelic music=audio hallucinations. jk
Posted a couple days ago in the music on dissociatives thread, but same thing for all intents and purposes. Some of the most psychedelic music right now is psydub/psybass/psystep and whatever else they are calling it, it seems to be evolving too fast to be pinned down. Merkaba Music and Shanti Planti labels are great places to start exploring.
Not bashing or anything but whenever I hear the term "psychedelic music" generally people are referring more to this kind of stuff
Honestly though, lately I've been caught in the notion that pretty much any and no music is psychedelic, mind manifesting music to me. It's all about the set and setting anyhow. Some people just like to label their productions somehow especially psychedelic, esp the rock/stoner community it would seem.
