1.psychedelia is a state of mind so i think that "psychedelic era" not neccesary means the typical psy-trance u might like,but i can clearly understand your question..
2.i found Qlippoth HIGHLY psychedelic
3.yup Derango is the real definition of modern psychedelic trance @ our days,of course you can hear still hear Filteria,Lost Buddha,nu MFG& Lani..
4.yup i agree x-dreams interface album is mostly electro/techno,but if u clearly hear it u can "travel" with the industrial techno sounds of machines & real cyperpunk and sci-fi atmospheres..
5.i think you might be more confused now,BUT as d-dave quotes "We do care for psychedelic and weird sounds. Strongly."
