Psyphoria - old school hippie tits
I think set and setting and stress level makes more of a difference than the music itself, I've been in deep psychedelia and found negative music laughable or simply irritating...however if I was stressed and in a strange environment and was exposed to the same music it could be overwhelming...
This next song reminds me of LSD, there's this sinister insanity piece to the experience which is expressed in the tones and feel of this song, I mean it's not always there, most LSD is fairly euphoric or psychoanalytical, but there's this stressed brakedown in some deep LSD experiences, it's like losing your mind, watching the world burn, and in a strange way loving it as you lose it...
Doors - not to touch the earth
I've never listened to these songs while on a psychedelic, so I'm not sure exactly what reaction they would inspire...
Cattle decapitation - regret and the grave
Cradle of filth - Funeral In Carpathia
Suffocation - Jesus wept
The locust - Plague Soundscapes
Bongzilla - gateway
However this next song has always reminded of high dose psilocin, when all of reality falls to pieces and you are in a half-enlightened half-insane in frantic scramble to sort things out...
Eyedea - the dive
Then there's some electronic music:
Shpongle - head in a fish tank
Im not sure how true this is, but I heard The CIA uses this next artist in its torture programs, this English musical and visual arts group might drive you mad on Psychedelics...the CIA locks people in dark rooms, deprives them of sleep and plays this band (as well as many others, like the Barney "i love you" song ) on constant loop as a means of torture, or at least that's the rumour I heard...
throbbing gristle - discipline
Maybe even explore stuff like this:
Astral Projection ☆ Binaural Beats + Isochronic Tones
This next band is an all female British crust/metal band dedicated to the DMT containing entheogenic decoction ayahuasca:
Iowaska - vine of souls
Again, I've never listened to any of this stuff on psychedelic compounds, and it doesn't fit with the other music that was posted, but may be interesting....
