Rock is a WHOLE 'nother genre. Rock fans don't care for choreo, lights, etc. They care for the voice and emotion that is conveyed. And of course these poptards wouldn't know about it, their faves barely dance right, struggle to sing while at it and have a lot of stuff to dstract their audience from it. Sad.
Anyways, Lady Gaga slaying the performance! The vocals!!! And she's a chameleon, see how she adapted her stage presence to the Rolling Stones one? LEGEND.
