One of the best vocalists out there today is Jessie J (real name Jessica Cornish). A contemporary of Leona Lewis and Adele, but with a far more eclectic and (I’d say!) interesting style. A little known fact about her is that during her teens she suffered a stroke!
This is one of my favourite pieces of hers, and grew on me within a few listens. Yes, it is a pop-piece, but it’s a lot of fun.
FYI the reason she is sitting down in this video is that she broke her foot around the time of this tour, and a throne was brought in to create a suitable place to rest her leg while also keeping the setting appropriate for the gig.
