Wow, jealous of your brother's first concert being a Rammstein show. You do know you are setting the concert bar pretty damn high to be met after taking him to this show eh? Seriously, Rammstein's live show blows everything out of the water.
But yeah, They have been touring machines for 2-3 years now. Looking forward to them actually taking a nice break and getting back into the studio to make some more music.
