Click on the link below and play DSB... It is from a Japanese concert (a lot of us have this concert).
It is a smaller venue, and Perry sings in a relaxed state, not having to try so hard to create volume. I especially notice where he sings "Living in a LONELY world". That line is pretty hard to hit perfectly, for me anyway. He nails it better than any other concert I have heard.
This wasn't the most energetic show I ever saw, I think Perry may have felt a little under the weather. I seem to remember him popping his ears a couple of times during the concert.
All of this to say that I prefer a more relaxed vocal, like this, or studio work. In any concert, you will try to give more volume to your voice than in a relaxed studio (Or am I totally wrong here, singing artists?).
Oh yeah, here's the link:
