Keys performed and taped her installment of the MTV Unplugged series on July 14, 2005 at the Brooklyn Academy of Music. During this live session, Keys added brand-new arrangements to her original songs such as "A Woman's Worth" and the funk-driven "Heartburn", and performed a few choice covers. Part of Keys' audience also included her guest performers; she collaborated with rappers Common and Mos Def on "Love It or Leave It Alone", reggae artist Damian Marley on "Welcome to Jamrock", and Maroon 5 lead singer Adam Levine on a cover of the Rolling Stones' 1971 "Wild Horses".
In addition to a cover of "Every Little Bit Hurts", previously performed by singers such as Aretha Franklin and Brenda Holloway, Keys also premiered two new original songs: "Stolen Moments", which she co-wrote with producer Lamont Green, and "Unbreakable", the album's lead single, which peaked at number four and number thirty-four on the Billboard Hot R&B/Hip-Hop Songs and the Hot 100 respectively. It was more successful on the Billboard Hot Adult R&B Airplay, where it stayed at number one for eleven weeks in late 2005. The session was released on CD and DVD on October 11, 2005. Known simply as Unplugged, the album peaked at number one on the U.S. Billboard 200 chart with 196,000 units sold in its first week of release. So far the album has sold one million units in the United States. The debut of Keys' Unplugged was the highest debut for an MTV Unplugged album since Nirvana's 1994 MTV Unplugged in New York and the first Unplugged by a female artist to debut at number one. It was nominated for four Grammy Awards in 2006: "Best Female R&B Vocal Performance" for "Unbreakable", "Best Traditional R&B Vocal Performance" for "If I Was Your Woman", "Best R&B Song" for "Unbreakable", and "Best R&B Album". It also won three NAACP Image Awards: "Outstanding Female Artist", "Outstanding Song" for "Unbreakable", and "Outstanding Music Video" for "Unbreakable".
