Before Iron Maiden concert began

The stadium was open for public at 5pm and we were there around 7pm.
From outside the stadium, we heard lots of echo of some bands playing but the first two were not so good.
We took a work around Gårda tills we heard Sabaton playing (around 8pm). They sounded quite impressive and we decided that is time to enter the stadium. The Iron Maiden's Final Frontier concert started around 9:15pm.
