After the initial Goblin split in 1979, Claudio released excellent Italo disco records under his own nam, but also with Crazy Gang or Vivien Vee. He also contributed soundtracks like this one. Dance of the Demons (Italian: Dèmoni) is a 1985 Italian horror film directed by Lamberto Bava and produced by Dario Argento.
The main title is very dramatic, though dancable. On your next Halloween party this will be the climax of the evening.
The video is nice as well giving Dario Argento a short appearance in the beginning and projecting Claudio to be part of the movie. Enjoy it if you can.
