Cecilia Bartoli never does crossover. Her content is always very heavy and serious, she just does it in a way that it seems like something written last week.
However, I want to suggest that should she ever decide to do crossover, an album of authentic Flamenco singing would be fascinating. When I see Flamenco, I am naturally interested in the singing and guitar playing. It might suit her. She could save this for when she is older and has nothing else to do.
In the USA we don't get Maria for a while. We are limited to sections on Cecilia's web site. She is working her magic.
