After performing at the first Gothic Meets Klassik festival 2012 at Neues Gewandhaus, Leipzig,[1] 'Die With You' and 'Ein Augenblick', two of the eight songs played were played in their classical style during their Monument tour.

The response to both the Gothic Meets Klassik and 'Once in A Lifetime' performance was positive, and Blutengel began a classical tour with the 'Monument Ensemble' performing the eight songs from Gothic Meets Klassik, plus five songs rewritten for the chamber ensemble.

[4] From this came 'Black Symphonies', and a new song entitled 'Krieger' (Warrior) with 'Legend' (Actually 'Legend Part 2' from the Monument bonus disc) and 'Monument' serving as an intro and outro to the album.

The DVD has four performances from the Gothic Meets Klassik, including 'Die With You' and 'Ein Augenblick' which were omitted from the album itself.

The box set contains the CD+DVD, a Black Symphonies T-shirt, a signed page of sheet music from 'Reich Mir Die Hand' and the Krieger single.
