Psychedelics can be an great tool to accelerate development towards self-actualization, but of course it isn't necessary. It's possible to get glimpses of life without the distortion of your person's labels and judgements. The reason for that is because when under the influence of a psychedelic drug, all sense perceptions are so enhanced there is a lot less room for thinking a.k.a. the rational mind. We call a chair a chair so we don't have to really see it anymore, that's what the mind does, labeling. But if you look closer the chair is actually oneness disguised as a chair. Oneness is all there is and it's is everywhere. We just can't see it because our mind divides everything into abstract stuff, labels and judgements. Yet that separate state feels like our normal state because everyone is in the same illusionary boat.
It is the separation that prevents one from seeing oneness in everything. It's the same with (listening to or making) music. Suddenly there is not you listening to the music anymore, but you become the music. You merge with the sense perception, as oneness. You can certainly get glimpses of that during a trip.
As for psychedelics and music, even though I kind of hate to say it, personally music sounds much deeper when tripping. I'm not saying it's impossible to feel the music as intensely when not under the influence, but for most people it is like that because most people are stuck in their mind (me included), so the real beauty doesn't shine through most of the time. I think I only had a handful occasions where I was sober and I felt an immense amount of joy from listening to music, like I wasn't myself anymore, like I really felt it for the first time.
