I have not read the book but I used to go to a club like you described! It was called Heaven & Hell and had a lush heaven room with morning trance leading to chillout and a fantastic hell room with techno leading to gabba! It was an ace concept but not quite to my musical tastes.
Don't worry, gaywhale (loves whale dick [sorry just love that sig]) has no idea what is psychedelic! Even with such an open concept where just about any answer is right, his is wrong
