Saw Sting the end of June with the Orchestra. Was one of the most enjoyable concerts I've attended. It really was a feature of the artist and actually hearing them sing instead of just belting out tunes in front of a wall of sound.
Was concerned that without people filling the upper bowl the acoustics would be bad (like they were for the Springstein folk band concert a couple years ago that we had to walk out on), but it was phenomenal. The clarity of his voice allowed hearing those neuances you pick up when listening to the albums in the pristine recording studio. If you're a fan of his, I couldn't recommend it enough.
