It contains new versions of her hits, many with her band also called Nena, some of them duets with other singers including Kim Wilde, Joachim Witt and Udo Lindenberg.

[7] Both releases exist in either standard or limited edition, the latter being supplemented with a bonus CD of live tracks.

[8] The songs on the bonus CD are also reworked, suggesting that Nena may have planned to update more of her back-catalogue, although there have been no further releases in this vein.

While Nena remained active and popular after the demise of the band in 1987, releasing several albums for adults and children, she was unable to recapture the chart success she enjoyed in the early 1980s.

Nena has sold more than 1.5 million copies worldwide, making it one of the best-selling albums by a German artist in the new millennium.

It was not until the follow-up studio album in 2005, Willst du mit mir gehn, that Nena finally broke the 1980s' monopoly of her greatest hits and concert favourites.

The show ran for nearly three hours, during which Nena invited many friends and fellow musicians to sing along with her: Joachim Witt, Udo Lindenberg, Kim Wilde, Westbam, Markus Mörl, Hartmut Engler, Rosenstolz, Mike Tait, Howard Jones, and TokTok, as well as the surviving members of Nena band: Rolf Brendel, Uwe Fahrenkrog-Petersen and Jürgen Dehmel.

The second DVD contains footage of Nena and her band on tour, interviews, and music videos for the new versions of the songs.
