Review
Band: Sidious
Album: Malefic Necropolis
Genre: BM
Country: U.K 🇬🇧

What can I say… Malefic necropolis is now easily one of my favourite albums from the IFP album catalogue, which say a lot!

Read my thoughts on the album over on my webzine now. I gave it a grand 9/10!

Ahead of our upcoming appearance at FILL THE VOID at The Black Heart, London, we have an important update for those who will be in attendance.

Due to touring commitments with @hecateenthronedofficial, our own Valdr will unfortunately be unable to make this show. But worry not — we have recruited MATT CROTON, of @trivax_official and @wyrdstaef fame, to reinforce SIDIOUS on drums for this night of nights.

Valdr states:

“Matt is an incredible drummer and has been a close personal friend of mine and the band for many, many years now, and there is no one else I would trust more with ensuring that you are given the best possible SIDIOUS show while I am away. The band is in very good hands with this man behind the kit, and I am certain you will give him the warmest welcome as SIDIOUS descends to the Necropolis once again in the capital!”

The full lineup for FILL THE VOID is now solidified with the addition of @evildungeoncrawler, @vestia.band and @arrogantdestruktorblackmetal.

Secure your tickets now.

NEW SHOW: FILL THE VOID ft. CODE, WOLFBASTARD, SIDIOUS & MORE TBA

We were as gutted as you all were when we heard about Cosmic Void’s postponement, and when we heard that the ever brilliant @codeblackmetal were left in need of a show, we figured why don’t we step in to fill the void ourselves, with @sidious_official and @wolfbastard_official stepping in to join the party too… early doors with MORE tba

Tickets live on Dice now… only £15 adv !!

Words shared by Dave Wolff of @asphyxiumzine on our latest opus ‘Malefic Necropolis’ 🔥

“Their style is intricate, complex, and enigmatic, yet accessible and not prone to be mired in misanthropy grandiosity Instead they envelope their ability in an aura of occult mystery that invites listeners to dive deeper. As much as their songwriting, their atmospheric pieces I was talking about, more like interludes, show that Sidious is far from a stagnant paint-by-numbers black metal band. They’re one of those bands that skillfully adjust their abilities to suit each song’s needs. The differences are subtle but make all the difference in the big picture, adding depth and nuance to the overall experience.”
