@KellyFan4Lyfe08 i agree with you, ima guitarist, ive been playing for 7 years and i have no look, i either walk around, sit of just stand, no guitarist should have a look otherwise the show would be boring, im on your side with this one :)
I feel like the guitar just inhibits her movement which makes her concerts feel so intimate. She moves around to make eye contact with everyone. I would be nice if she played on a ballad though, sitting on a stool maybe. You can also hear her trying to rock this out, definitely signs of what was to come on Breakaway!
