Mariah and Stella are being very smart here.., especially as Mariah means many things to many people. Each subsequent tour/residency allows her to capitalise on the variety within her discography.

1. Vegas is for the middle of the road audience who love her classic balladry.

2. Sweet Sweet Fantasy Tour is for her contemporary millennial audience who enjoy the ballads, the Hiphop, the dance remixes and the RnB jams.

3. While the Lionel Richie 'special guest' slot is to appeal to her much older legacy audience, hopefully by capitalising on the jazz piano torch balladry that she's starting to excel at i.e. Thank God I Found You freestyle.
