I've always loved Nine Inch Nails, so I'm biased towards the music. So I can easily say in the music category, the concert was awesome.
But jesus christ at the light show and visuals. It was like anything I had ever seen.
For some songs, the band would be between 2 screens, where stuff would be projected on to, and they would even be able to iteract with the visuals. It was so so so awesome.
