I'm back with some old Infected Mushroom specific album recommendations.
1200 Micrograms - “The Time Machine” or “1200 Micrograms”
Lots of spoken word and rock instruments like some old IM
Astrix - “Red Means Distortion” or “Artcore”
Astrix is the other “popular” artist, you mentioned some of his stuff already.
His compilation album “Psy-Fi Book of Changes” features a bunch of different artists so there's lots of new stuff you can try out. You can dive deeper on other artists there if you like any of it.
Hallucinogen - “Twisted”
Has slower and darker music a bit like IM
Shpongle - "Museums of Consciousness" or “Are You Shpongled?”
Same category as above
At the end of the day though, IM songs like Dracul and Albibeno are pretty unique. The whole Converting Vegetarians album has a (fantastic) sound that is unique to their band and isn't replicated much elsewhere. In case you haven't listened to Converting Vegetarians II, make sure to check that out.
I enjoy Astral Projection's "Another World" but it's pretty airy and upbeat compared to what you listen to. Astrix's “He.art” I really enjoy but its newer and faster.
