Most of the stuff here is either old goa or trance.
There are many psytrance subgenres, however, a few names here:
Old Goa: Hallucinogen, Astral Projection, Cosmosis, Green Nuns of Revolution, Eat Static..
New Goa: Filteria, MFG, Kethzal.. (check suntrip recs, they are the best for this subgenre)
Full On (aka cheese): Tristan, Laughing Buddha, Avalon, Atmos, Fungus funk.. (alchemy and liquid recs are a good start)
Night time: Psymmetrix, EVP, Neutral Motion, Burn in Noise, Dirty Saffy, Beardy.. (wildthings and bom shanka recs are the best imo)
Forest/organic: Atriohm, Ajja, Electrypnose, Ianuaria (parvati, peak, blue hour sounds recs should keep you busy for a while)
Suomi: Texas Faggot, Luomuhappo.. (Faerie Dragon and Exogenic are leading recs for this genre)
Dark: Orestis, Furious, Cosmo, Kindzadza
Then there's the progressive bit that you might like mre if you're coming from a techno background. It's split in 2 subgenres:
cheese: Ace Ventura, Flowjob, Vibrashere, Liquid Soul
dark: Sensient, Grouch, Kromelur (Zenon recs is a must)
than there are psy breaks where I would mention Slackbaba, Headflux and Far Too Loud
Shpongle are not psytrance by any means, there's a whole psybient (ott, bluetech, shulman, kaya project) and psydub (international observer, ashtech, gaudi) genre there.
If you like them tho, I would raccomend Younger Brother's (which is Simon Postford rock-ish project) first 2 albums that were even considered the new Pink Floyd sound for a while.
Personally I always enjoyed most flying rhino releases (there was a time in the 90's when they had a lot of their releases for free on their website) and almost every T.I.P. record.
