I can also add to the discussion....O is certainly a magnificent track, worthy of all the praise I read above. Possibly my favourite Planisphere track, but when there are so many good ones how can I call it?
For me - 'Moonshine' is the much better track,and the ultimate Planisphere track imo....i don think anyone else made that style of Trance ever,with the long atmospheric breakdowns and the kick finally coming back in. There has been quite a few different structures of Planisphere tracks - 'O' is another style while 'Nothingslave was totally different. But i just love that long breakdown style he had with Moonshine and a number of others like Totem.
