Katy Perry's 'Unplugged' Premieres On MTV.com

Accompanying album will be in stores Tuesday.

The album won't be in stores until tomorrow, but you can hear [url id="http://www.mtv.com/music/unplugged/?artist=katy_perry"]Katy Perry's "Unplugged"[/url] performance Monday (November 16), on MTV.com.

Perry's set features stripped-down performances of her biggest hits (including a jazzy reworking of "I Kissed a Girl" and "Waking Up in Vegas"), and a pair of new songs: "Brick by Brick" (which is not to be confused with the Paramore tune) and a cover of Fountains of Wayne's "Hackensack."

The "Unplugged" special also features an extended interview with Perry in which she tells the stories behind her hits. MTV will also air highlights from the show across multiple on-air channels, including mtvU, MTV Hits and MTV Tr3s. Oh, and in celebration of the digital premiere, MTV's morning all-music block, "AMTV," is currently airing performance videos taken from the taping. Palladia, MTV's high-definition television channel, will also air a half-hour version of the special on November 27 at 9 p.m. and midnight ET/PT.

The entire "Unplugged" performance will be available starting Tuesday (November 17) in both traditional album format, and a deluxe CD/DVD edition.

Fans can consider all this a holdover until Perry releases the follow-up to her massive One of the Boys album, though, by all accounts, it's sounding like a very unacoustic affair. She's cited Swedish pop acts like the Cardigans and Ace of Base as inspirations for the album, and she's reportedly writing songs with none other that Weezer's Rivers Cuomo, who knows a thing or two about making the party-hearty jams.
