Context paragraphs:
Endorama: Endorama is the ninth studio album by German thrash metal band Kreator released in 1999 by Drakkar Records.  The gothic metal influences were the most prominent on this release, and Lacrimosa frontman Tilo Wolff provided guest vocals on the title song.

Sehnsucht (Lacrimosa album): Sehnsucht is the tenth album by the German gothic rock duo Lacrimosa, released on 8 May 2009.  Singer and producer Tilo Wolff wanted to create an album that was less conceptual and more spontaneous than the previous releases by Lacrimosa.  Therefore, "Sehnsucht" features a great variability of musical expressions like a sarcastic track "Feuer" and the tender song "Call Me With The Voice Of Love".  The planned release of a vinyl format album was cancelled shortly before the final release of "Sehnsucht".

Ferdinand Wolff: Ferdinand Wolff was born in Germany in 1812.  Wolf was a journalist by profession and a proletarian revolutionary.  He joined the Communist League and became an editor of the "Neue Rheinische Zeitung" in 1848 and 1849.  He was a close friend and associate of both Karl Marx and of Frederick Engels and he sided with the Marx and Engels group during the 1850 split in the Communist League.  Wolf died in 1895.

Lacrimosa (band): Lacrimosa is a gothic duo led by German Tilo Wolff, the main composer, and Finn Anne Nurmi.  They are currently based in Switzerland, but originally from Germany.  Originally counted among the bands of the Neue Deutsche Todeskunst genre, Lacrimosa have developed their style more towards powerful metal, but Gothic elements still remain.

Die Freie Bühne: Die Freie Bühne, (German: "Free Stage") was a subscription-based theatre club founded in Berlin in 1889 by 10 writers and theatre critics supervised by Otto Brahm for the purpose of staging new, naturalistic plays that were either censored, not commercially viable, or not otherwise commonly produced.  The 10 founding members were: Otto Brahm, Maximilian Harden, Theodor Wolff, Julius Hart and Heinrich Hart, Paul Schlenther, Julius Elias, Julius Stettenheim, Paul Jonas and Samuel Fischer.  Inspired in part by André Antoine's Théâtre-Libre in Paris, Brahm's company gave private performances to subscribers only.  Performances were held on Sunday afternoons.  The "Freie Bühne" opened with a production of Ibsen's "Ghosts" (1881), in September 1889.  Later productions included works by writers such as Gerhardt Hauptmann, Arno Holz, Émile Zola, August Strindberg, as well as dramatic adaptations of Tolstoy.  The "Freie Bühne" closed in 1894, mostly due to the fact that larger, commercial theaters in Berlin had by then begun to embrace the new theatrical styles that the "Freie Bühne" had championed.  Together with the Théâtre-Libre in Paris and the Independent Theatre Society in London, the "Freie Bühne" inspired a number of smaller, subscription-based theatres, known collectively as the Independent Theatre Movement.

Two Witches: Two Witches is a gothic rock band from Finland, formed in 1987.  As with several other late 1980s bands (like Dream Theater and Nosferatu), Two Witches started basing the main part of their appearances and lyrics on the vampire imagery.

Their last work is the album "Goodevil", published in 2014.
