The specific album you mentioned, has two tracks I like (Heavyweight and Suliman) because I saw a fellow on YouTube using a guitar to 1:1 the riffs. It was that good that I donated to him. But otherwise I've never been much of a fan of IM. I find they're overrated.
When I think of goa trance I think of names like Astral Projection, Green Nuns Of The Revolution, Hallucinogen, Man With No Name, Miranda, Prana, Transwave and many of these dabbled into the psytrance genre. Some came back!
I'll mention some of my favourites: Hallucinogen live at DNA Lounge (2001?), Paul Oakenfold's Essential Mix ('Goa silver and gold mix', '94), any 90s live set by Astral Projection (there are many), and Imperial Project / Goa Syndrome (all of which were released on MP3.com). Also, any remix by MWNN and AP is gold.
Although I do like the variety that has developed, especially when there's multi-room club and it's possible to walk around and find whatever fits your current mood and energy level.
My favorites to put on while focus working are Classical Mushroom and Outdoor Party Vol 3. The latter can be hard to find for some reason but imo is their best.
They host an annual dessert rave and go for a 4 hour retro set starting just before the sun rises. Been there, felt like I've seen the light. It was spiritual.
You're going to have to trust me that as far as Israeli producers go, IM are neither cheesy nor commercial.
> I don't consider them truly representative of psy-trance, at least the eurocentric versions I listen to.
Ehhh, that's veering way too close to "metal genres" territory for me
