Despite having seats so, so far away from the stage we had a great time.
The band were brilliant - Dave Grohl has an insane amount of energy and they all came across as having a real respect and appreciation for their fans.
The stadium has a bit of work to do sorting out the audio issues if it wants to become a good venue for concerts but overall it was a really fun night. Three hours and six encore songs later, I was pretty glad I had bought myself such a good birthday present! :)
