Folks like to play with Monica, Aaliyah, and Brandy like Whitney Elizabeth Houston aka THE VOICE didn’t co-sign all three of them.
Aaliyah - handpicked by Whitney for Sparkle before her passing and the role was recast with Jordon Sparks.
Brandy - Whitney was originally picked to be Cinderella but due to ageism, felt Brandy would be the better pick. She was her Fairy Godmother on and off camera.
Monica - Whitney let it be known live at a concert “I’ve been in the studio with Monica and she ain’t scared of me”, the same concert she grabbed 16 year old Monica and said “Shoop for me”. And Monica did it flawlessly. No warmups. Unrehearsed.
All three are responsible for a lot of what you see/hear in R&B/Pop today.
