I saw them in copenhagen the 14/6, and i really liked it, except for robert fripps part of the show.... when it started he sat down in a corner of the stage playing nearly the same thing for about 45 min. and damn, people were bored.... but then Vai entered the staged and rocked the place.
about an hour later satriani did a great job as well, and they all finished playing together, and still with robert fripp sitting totally in the back of the stage hiding in the shadows ...

but with no doubt a great evening :) except for the start ^^
