Carey would once again refuse to embark on a world tour to promote the album. Although she credited stage fright and the vocally challenging nature of her material, speculation grew that Carey was a "studio worm," and that she was incapable of producing the perfect pitch and 5-octave vocal range for which she was known. In hopes of putting to rest any speculation of her being a manufactured artist, Carey booked an appearance on MTV Unplugged. The show presented artists "unplugged" or in a stripped setting and devoid of studio equipment. Days prior to the show's taping, Carey and Afanasieff chose to add a cover version of The Jackson 5's 1970 song "I'll Be There" to the set-list. On March 16, 1992, Carey played and recorded an intimate seven-song show at Kaufman Astoria Studios in Queens, New York. The acclaimed revue was aired more than three times as often as the average episode. It established Carey as a viable live act, with critics heralding it as a "vocal Tour de force". Carey's live version of "I'll Be There" became her sixth number-one single on the "Billboard" Hot 100 chart. Sony capitalized on its success and released it as an EP. It earned a triple-Platinum certification by the Recording Industry Association of America (RIAA), and earned Gold and Platinum certifications in several European markets.
