That stage was so too big (and looked so wrong for the band) it's ridiculous. I doubt it would have been possible, technically, to put everyhing in front, with not much time to think about it. I just can't imagine the band wants that distance, usually they are very close to the audience.
It seems they finally changed some melodies to adapt to JLBs voice. I'm glad they do (well, I always loved his middle and darker range the most), I hope it's not a problem for the majority of the fans.
