I hope she could shake things up for her performance at the Jazz festival. Not another typical Mariah performance, but a more boldly, organic, serene one. She could change a bit the arrangements for "Hero" and "We Belong Together", and it's a perfect opportunity for her to sing "The Wind"! She should also do a cover or two, like "Lullaby of Birdland" ("Don't Explain" didn't suit her in my opinion).
I read about replacing Celine at Vega, but there were also rumors about residency in Connecticut or Atlantic City.
And I remember reading an interview with Mariah where she'd mention she would like to get back to the big screen, so maybe another movie this year?
