Her voice and stage presence is awesome and well worth the effort to attend. This is my first time at the Keswick, which is a delightfully intimate venue for this type of concert.
There were a couple of negatives: the concert started about 40 minutes late. This was probably due to late arrival of the star, but was never explained to the audience. Instead, there was an opening act that looked very improvised, and some obvious stalling by the audience before the show began. This gave a bit of a disjointed aura to the show overall.
It wasn't necessary. Ms. Cole and her team need to trust her audience, which is extremely supportive of her. And again, her music -- even as she recovers from major surgery -- is awesome.
