Watching this 27 years later and I'm so proud of Mariah. She gave the absolute best performances of My All (SNL) and Butterfly (Letterman) in her hometown in that period - it's really very touching. She is an unbelievably talented woman.
The textures, color, agility and range of her voice is straight up eargasmic. While the longing, sadness and sultriness of her melodies tug your emotions in all directions.
Oh man those low notes at the end. She wrote the song like that on purpose she knows that is a very very dangerous path to go in a song. Just a master piece !
