A list of every
Unplugged concert held to date. From there you can click on the artist and find if they had their performance released.

MTV will revive the series when Alicia Keys' Unplugged special airs on MTV on
September 23,
2005. It will be the first 'Unplugged' for Alicia and the first for MTV in nearly three years. Special guests for the performance include
Mos Def,
Common,
Damian Marley and
Maroon 5's
Adam Levine. The show is scheduled to be released on
CD and
DVD in
October 2005.
Interesting. I wonder if they will keep the series going again?
