I was there, but only just! We had a major crash on the M1 on the way there, writing off the car, and we lost three hours of the journey. By some miracle, we got there half way through Escala's set in the end (we borrowed another car). I had mixed feelings about the show. The start felt really false, and as a Sarah Brightman fan, the blatant "inspiration" from her tours was a bit irksome. There was nothing that Katherine did in that concert, that Sarah didn't already do in her Eden and Harem tours in 1999 and 2003. But since the British public do not attend Brightman tours, I suppose the classical audience will find KJ's concert highly original, and good for them.
I was impressed by Katherine's energy, and her own participation in the dancing. Her acrobatic displays were also impressive, and of course, her voice didn't really falter. But the first half was really dull and boring (apart from the acrobatics), but the second half really picked up. I often felt that the dancers she had were just distracting (as if her ever evolving cleavege wasn't enough to distract! That pink dress didn't leave much to the imagination!) You were, half the time, too busy looking at what everyone was doing on stage, forgetting to listen to Katherine. Indeed, I've forgotten half the songs she performed already. All I remember are the visuals. :/
I need more time to sort my thoughts out on this before I write up a review. But I am starting to see why Sarah Brightman fans get annoyed by Katherine all the time (even on the concert description she was described as the world's most successful female classical crossover artist! Err...)
