7. Mariah Carey (1992)
By the summer of 1992 Mariah Carey had released two best-selling albums, but she hadn't promoted them with many concerts and there was a sense in the air that perhaps she was just a studio creation that couldn't deliver the good onstage. To put that notion to bed forever, her label booked an Unplugged show at Kaufman Astoria studios in Queens. The show featured hits like "Vision of Love" and "Emotions" along with a cover of "I'll Be There" by the Jackson Five, which was sung as a duet with backup singer Trey Lorenz. The special was such a huge success that MTV played it for years, and radio embraced the version of "I'll Be There. Lorenz remains a key part of her live band to this day and they continue to sing "I'll Be There" together.
