Can only comment on seeing live music saw the Stone Roses.
The stadium is geared up for handling large crowds, plentiful toilets and food and drink stands, can be a bit of a nightmare getting out and back to a train station.
The staff inside and out are very helpful.
as for seeing a live music event although it was a sold out gig it didn't feel overcrowded and as this was standing and unreserved level 1 seats you could stand or sit down if you wanted.
The sound inside the stadium is good.
Overall a good place to experience a live gig.
