I have seen Rammstein.....but I was sitting outside a bar in Ostkruez some 10 miles away from the Olympiastadion where they were playing...we could see their stage pyro lighting up the sky.I did similar with a chum few years ago. We went to arena shows as much as we could.
We saw Aerosmith, Maiden, Rollins Band.AC/DC, Soufly (though that was at Concorde 2! They usually play massive stadiums. It was carnage )
Rammstein was also a standout for me.
Hoping to see them in Tubthumper country this year. I can’t recommend their show enough. Mind blowing.
I have seen videos of their shows...which are nuts. I read they deliberately design their stages so that they are taller than the stadiums they are in.
