In general, I think I miss the songwriting aspect most. Infected Mushroom really nailed it, which is why they're so popular. Nowadays, I can only find the Japanese doujin music scene among those that regularly mix and match psytrance with various other genres.
A few other recs going more in that direction:
- Talpa (https://sundancerecords.bandcamp.com/album/when-the-somberne...)
- Jerico's Law (https://juno909.bandcamp.com/album/another-law)
- Migma Shelter (https://www.youtube.com/playlist?list=OLAK5uy_l3dfWAOgloDDde... -- j-pop psytrance!)
- Hilight Tribe (https://hilighttribe.bandcamp.com/album/temple-of-light)
- Koxbox (https://koxboxmemo604.bandcamp.com/album/the-great-unknown)
- Hallucinogen (https://hallucinogenmusic.bandcamp.com/album/the-lone-derang...)
- And finally, the best hi-tech work I've ever heard. Sephax - Electric Currents (https://alice-drecords.bandcamp.com/album/sephax-electric-cu...)
