This was a private production rehearsal for the A Thousand Suns World Tour. The band ran through the full A1 headlining setlist, but it is possible they did several takes of a few of these songs, especially the newer songs and possibly even skipped a few older ones. This seems to be a structured rehearsal though (with a set setlist to get ready for the tour), unlike the one to start 2011 where the band mainly just rehearsed new songs.
Since there were passes issues by MLK, the German promoter, we are guessing that they allowed a few fans in to the rehearsal. This might not be correct, but we are listing the show in case that is true.
