Turn Around, Dark Eyes
You've heard the original version of Bonnie Tyler's "Total Eclipse of the Heart," you've heard the disco remix, now hear the 80s power ballad sung in German as a duet between an innkeeper's beautiful daughter and the king of all vampires.
It's called "Totale Finsternis" ("Total Darkness"), and it's the opening song from the Second Act of Tanz de Vampire (Dance of the Vampire), a musical remake of the 1967 Roman Polanski film The Fearless Vampire Killers. The original production, which premiered in in Vienna, Austria in 1997, was directed by Polanski himself with music written by Jim Steinman (the guy responsible for many of Meatloaf's hits), who also wrote the lyrics for the musical's English version. Unbelievably brilliant.
PS-Thanks to Kat for tipping me off to Carpe Jugulum, which has every single MP3 including the demos, the European performance, the broadway production and so much more. She especially recommends listening to "Dance of the Vampires" in the English and "Carpe Noctum" ("Seize the Night").
