from a psytrance point of view allmost nobody comes close to the finnish and australien sound (like anoebis already mentioned).
Mandalavandaz : hongkong nightlife, alienated,some haltya stuff, eraser vs yöjalka, texas faggott (especially album nr2), derango. I think compared to those ones pleiadians, green nuns, psychaos,........ is onedimensional music.
