It's interesting to hear Kelly sing the blues again, because realistically we haven't seen this side of her since Idol and it's a damn good side to see. Her voice suits the genre to a tee and she pulled the performance off effortlessly.
With the arguable dip in Kelly's output recently, a change in genres may not be the worst idea. There is a sense that she's become disinterested in pop which could account for the lacklustre effort that was 'Piece by Piece'. Although I'd much rather hear Kelly-pop-magic in the vein of 'All I Ever Wanted' again, if her preference is for blues (or country, as has been much hinted at), an album with her full commitment and enthusiasm would be preferable to a repeat of her latest studio endeavour.
What do YOU want to hear Kelly sing next?
