MTV Unplugged is the first live album by American singer-songwriter Katy Perry, and was released by Capitol in the United States on November 17, 2009. The two disc CD/DVD package comprises stripped-down songs performed by Perry for MTV on July 22, 2009, in New York City as part of the MTV Unplugged series. The album features rearranged takes on Perry's hit songs like "I Kissed a Girl", "Waking Up in Vegas", and "Thinking of You," as well as two brand-new songs, Perry's version of Fountains of Wayne's "Hackensack" and an original song, "Brick By Brick." The DVD also features exclusive interview footage. In Brazil, unlike the US, it was released in DVD/CD format instead of CD/DVD format.
