Carey performed this on her 1992 MTV Unplugged
special. Despite releasing two hit albums, the singer hadn't embarked on a major tour as she feared the strenuous nature of her songs would damage her voice through repeated performances. Many critics, still feeling the burn from Milli Vanilli's lip-syncing fiasco
, were wary of her excuse and wondered if her otherworldly voice was the result of studio trickery (even though she had proven herself many times through previous live performances). To promote Emotions
and silence her critics, Mariah appeared on the live program to sing a handful of her hits. The bid worked, and the accompanying EP sold two million copies a month after its release and hit the four-million mark in 1994.
