Context paragraphs:
MTV Unplugged (Mariah Carey EP): MTV Unplugged is a live EP by American singer and songwriter Mariah Carey, released in the United States on June 2, 1992 by Columbia Records.  Following the success of Carey's previous two albums and the growing critical commentary on her lack of concert tours and unsubstantial televised performances, Sony BMG organised a performance show at the Kaufman Astoria Studios, New York on March 16, 1992.  The show, titled "MTV Unplugged", originally aired on MTV to help promote Carey's album "Emotions", as well as help shun critics who deemed Carey a possible studio artist.  However, after its success, the show was released to the public as an EP, with an accompanying VHS titled "MTV Unplugged +3".

MTV Unplugged (Café Tacuba album): Unplugged Café Tacuba is a complete live album (ninth overall) that was recorded in 1995 and released in 2005 as a CD/ DVD combo by Mexican alternative rock group Café Tacvba.

The MTV Unplugged album includes the selections "El Metro," "La Ingrata," "Esa Noche," "Una Manana," "Bar Tacuba," and others.

Live from the Sun: Live from the Sun is a live album released in 2000 by the American heavy metal band Dokken.  This album captures the reunited Dokken minus guitarist George Lynch at the Sun Theater in Anaheim, CA, on November 4 1999, running through a live set of mostly greatest hits plus two songs from the then-recently released "Erase the Slate" album.  A video of the performance was also released both on VHS and DVD formats.

Kermit Unpigged: Kermit Unpigged is a music and comedy record released by The Jim Henson Company through BMG Kidz in 1994, and the last album released by Jim Henson Records.  The record’s title is a clear parody of the MTV series “MTV Unplugged”, and the cover is a parody of Eric Clapton's "Unplugged" album cover as well.  The album consisted of Kermit and the other Muppets getting lost at a recording studio and encountering celebrities including Linda Ronstadt, with whom Kermit sang “All I Have to Do is Dream”, Vince Gill who sang “Daydream” with Kermit, Jimmy Buffett who sang “Mr. Spaceman” with Gonzo, and Ozzy Osbourne with whom Miss Piggy sang “Born to be Wild.”  The album ends with all The Muppets meeting back up and singing the Beatles song “All Together Now.”

One Live Night: One Live Night is a 1995 semi-acoustic live album by heavy metal band Dokken.  The reunited Dokken recorded the album during their 1995 tour.  The album went virtually unheard at the time of its release.  Released at the time when grunge and alternative rock were dominating mainstream rock music, MTV had no interest in featuring glam metal acts; so Dokken decided to do their own "unplugged" album.  This intimate performance included versions of "Tooth and Nail", "Into the Fire" and "Alone Again", as well as covers of the Beatles' "Nowhere Man" and Emerson, Lake & Palmer's "From the Beginning".

Unplugged (The Official Bootleg): Unplugged (The Official Bootleg) is a live unplugged performance by Paul McCartney, recorded and released in 1991.  Following the vastness of his world tour recently captured on "Tripping the Live Fantastic", McCartney relished the opportunity to strip back his songs and appear on the newly launched acoustic-only show "MTV Unplugged".  Consequently, McCartney was the first in a long line of artists to release an unplugged album.

Unplugged...and Seated: Unplugged...and Seated is a live album released by British musician Rod Stewart on 24 May 1993.

The unplugged versions of "Have I Told You Lately" by Van Morrison, "Reason to Believe", "Having a Party", and "People Get Ready" were released as singles, with "Have I Told You Lately" and "Having a Party" reaching success as singles.  A special collector's edition was released in March 2009 on Rhino Records.  This two-disc package included the DVD of the MTV performance with 13 songs while the CD contained 17 tracks including two songs ("Gasoline Alley" and "Forever Young") not on the original 1993 release.
