Well if something is the Most Psychedelic then it is in the number ONE spot. If you say shpongle is the most psychedelic music you have ever heard then people will automatically assume you mean everything else is NOT!
For me I usually find slower music more psychedelic
My thoughts pretty much
It doesn't sound like you really like too much chillout music. Or at least you are after a very specific style. Either way you are going to struggle finiding what you like.
try these tracks
1. Ra - Light Receiver
2. Intermix - Solar Temple
3. Astral Projection - Ambient Galaxy (Disco Valley Mix)
4. Cosmosis - Roswell
5. Goasia - Pray For Rain
6. Man With No Name - Azymuth
7. Filteria - Cloud Kingdom (Solar Fields Mix)
8. Aes Dana - Lysteria
9. Ra - Gates of Tiperath
10. Dimension 5 - Flow
11. Astral Projection - Still Dreaming (Anything Can Happen)
12. Jikkenteki - Ambiguity
13. Khetzal - Avasari
14. Mystery Of The Yeti - A Welcome To All Extra Terrestrials
15. The Infinity Project - The Answer
16. Hallucinogen - The Herb Garden
all of which I think have a goambient feel with maybe the last few tracks being a bit to soft for you.
