It sounds like it was simply a gig with bad sound and new band members to break in. Perhaps they simply could have done with a warm up gig somewhere - perhaps Las Vegas WAS the warm up gig!
It'll take them a few weeks to tighten up and then when they hit Europe they will be the mad unstoppable force we know and love.
Perhaps they are learning to play the old familiar stuff well before slipping in the new stuff (or maybe there isn't any).
Lets wait and see! They can only get better and better!
