The Black Light Bacchanalia is the twelfth album by New York heavy/power metal group Virgin Steele, released via SPV/Steamhammer on October 22, 2010 in Germany, Austria & Switzerland, and the rest of Europe on October 25, 2010 & on November 9, 2010, in the USA.

With a duration of over 11 minutes, "To Crown Them with Halos (Parts 1 & 2)" was the longest track Virgin Steele have ever recorded until it was surpassed by the 13-minute "The Ritual of Descent" from their 2023 album The Passion of Dionysus.

All music and lyrics by David DeFeis It is a long album...close to 80 minutes.

Once conquered by invading cultures, older Pagan deities become the demons from the new religion.

The Black Light Bacchanalia is a reversal of the sacred sexual customs, and the final desecration of the 'Goddess Principle,' switching from matrilineal descent to patrilineal descent, with the rise of the idea of the Mountain-Fire God...And it also has to do with ancient fears such as the fear of the sun not rising...Lyrically it is a kind of continuation of the story I told on the last album...Musically it is quite something else...
