I know there are 6 but the 2 Wishbone Ash concerts count only for one ... There is no order in them, I don't know among those which is the one I preferred ... I'd say the Marillion but not sure ...
Also saw Symhony X on April 19th 2003, was a nice show but not in my favourite 5 concerts.

Lots of rock or hard rock concerts: Metallica, Iron Maiden, Deep Purple, but these are non prog so I'll forget them ...
