She can no longer coo or softly croon nor can she perform her trademark gravity-defying vocal runs.
In addition to her vocal ability, Carey has been credited for her role and impact as a songwriter and producer.
Carey began conceptualizing a film project All That Glitters, later re-titled to simply 2001 , and wrote songs for other projects, such as 1997 and 2000.
Carey announced the second leg in October 2015.
