Muse aren't as popular in my country as in the rest of Europe so if there's anyone who knows lyrics to all the songs and sings along and moves a bit it's mainly people from abroad who stand in front rows. In 2012 i was in 2nd row, surrounded by people from Germany, Israel, Poland etc... The rest is there for Madness, PiB and Starlight We'll see in June if anything's changed.
As for Germany, I've been to 4 Muse gigs there, always barrier, and the crowd was pretty chilled tbh. I think the best ones are in the UK - Manchester 2013 was ace. Danish crowd was pretty wild as well - Matt's comment "this is the first time I've seen a moshpit during Madness" speaks for itself
