Yes copa she is very much involved when it comes to the designing of her costumes, dance moves and over concert stage designs etc. She apparently also does not actually make money personally from her concerts, the money goes straight back into the production of it to make it bigger and better.
I went to go see her @ the O2 arena when I went to the UK a few weeks ago. I can truly say it was one of the best experiences ever. She was on stage for a full 2 and a half hours!!!!! When she needed to have a break, she would work it into the show and still keep you entertained. For example, for a bout 5 minutes she lied down on the piano with her leg hanging off and her high heel on one of the notes. The drummer gave a beat and she would tap the key to the beat while the dancers did their thing to keep us entertained. Was brilliant.
I personally did not think she had a brilliant voice seeing that I mostly only know her dance tracks...but when she performed "Speechless" live on the piano, I got goose bumps!
So I vote.........BRILLIANT!!!! And if she were to come to Joburg I will definately go see her show again. And I recommend you guys do the same...even if you not a big fan....just go for the entertainment. It is worth it.
