I have a cd somewhere filled with modules, mostly from Traxinspace. I can put them to my share in Soulseek, if someone's interested. Not all of it is psy, there's also lots of ambient and hardcore modules...
I've been listening to psy for many years now but don't know much about "the scene" so to speak. But I would add some tracks:
Psychopod - Universal Mind (Or something else from the Headlines EP?)
Beat Bizarre - Pony Sauce (Or perhaps Brain Drain RMX? I think the whole Lewd album was highly original, though I haven't heard anything else quite like it..)
And then some minimal tracks by Shiva Chandra (or some sideproject?) and Intact Instinct. They were both very original, and I reckon Shiva Chandra was quite a pioneer in the (german) minimal trance scene which I love very much.
