On October 26, 2024, MOONSPELL performed their first-ever symphonic Orchestra show, dubbed “Opus Diabolicum”, at the MEO Arena in Lisbon, Portugal’s capital city. The band made history at this unforgettable live event, adding another magnificent chapter to both metal music made in Portugal and their very own legacy, while revisiting their classics and the bombastic album “1755” at a one-off, exclusive show and their biggest production to date. The heavy metallic power of the dark metal pioneers met the classical magnitude of the 45-piece Lisbon Sinfonietta Orchestra – one of Portugal’s finest orchestras – conducted by maestro Vasco Pearce de Azevedo!

Now, a year later, this monumental event can be yours to view anytime, available in DVD/Blu-ray, 2 CD, Black and Colored Vinyl and Digital formats via Napalm Records on October 31, 2025.

Following the epic previously-released live video for the band’s anthem “Vampiria”, today, MOONSPELL releases “In Tremor Dei” featuring the Orquestra Sinfonietta de Lisboa. Epic, emotional, and devastatingly heavy – this new live version of “In Tremor Dei” shakes the very foundations of MOONSPELL‘s pioneering metal sound, blending soaring melodies and crushing intensity: a once-in-a-lifetime performance!

Frontman Fernando Ribeiro comments:
“1755 was an essential album for the orchestral show and the very foundations of it are based on this portent record, Portuguese sung and thematic around the great earthquake of Lisbon, in the 18th century. It’s a track that captures the essence of the whole show and theatrics – Lisbon trembled again but the orchestra played on.”

“I have never been the one to push MOONSPELL into an orchestral direction“, Ribeiro recently admitted. 

“I mean, like any fan, I can recognise the impact Classical had over Heavy Metal (Quorthon, from Bathory, used to quote Wagner as his favourite “band”) and in my musical collection Mussorgsky, Prokofiev and Ravel, could be found, shoulder to shoulder with the aforementioned Bathory, Celtic Frost, Sarcófago or Maiden. But, I wasn’t a fan of the metal meets orchestra efforts myself and when I approached Jaime (Gomez Arellano) to mix this beast, I asked him: have you heard S&M and other “live with an orchestra” metal bands albums? We want nothing like that!

This is work of passion: truly the work of the devil (opus diabolicum): imperfect, unprocessed, untamed. A release made by friends to all the friends we have around this goth forsaken world and that in an arena in Lisbon or in a sweaty club in Texas, keep the spell going, until we are no more.”

No MOONSPELL fan, anywhere in the world, should miss their chance to add this rare and massive performance to their own collection! Pre-Order “Opus Diabolicum” now at
