"It’s Only Permanent paints a picture of a world teetering on the edge of seemingly inevitable destruction. All the while snarling guitars cut through with piercing riffs and grooves so dirty you can practically feel the rust crunching off of them...not interested in wasting your time though even as it seeks to take you through an entire cycle of crisis and relief followed by more turmoil and pandemonium...It’s an emotional tour de force that is worth holding onto every second for."
"It's Only Permanent is mainly distinguished by its predominantly calmer, gentle and beautiful sound...the music of Black Flak and the Nightmare Fighters is an introspective symphony...a beautiful album, completely worthwhile listening...If you are an enthusiast of modern experimental post rock, you will positively love this amazing work of art."
"...cinematic, harrowing and at times both frenzied and tragic. The four-piece ensemble utilizes dynamic shifts, tight drumming and a heavy use of effects pedals, creating a soundtrack to what could be a yet-unmade documentary about mankind’s conflict and grief...Once We Knew imparts a sense of stark nostalgia, and is as pictorial as it could be, at times capturing the feel of the war... an inspired, engaging debut release."
"...start the music, close your eyes and see...you'll create your own scenes from the gloomy pages of human civilization. It will be "silent film", accompanied by sublime, sad and mournful music. A minimalist rehearsal of soft melodies, dynamic cascading builds, gripping tremolo guitars, a steady solemn beat of drums, sweeping ambient textures and meaningful sample programming...the "cinema" you will see will be new and all your own."
"Once We Knew the World Well" - a moody work, emotional and expressive, very listenable, and in its stylistic niche clearly competent. For fans of post-rock and instrumental soundtrack music, it's definitely worth a try."
"...a high degree of perfection in the visualization of the delicate texture of the sound produced...as well as the musical image of the message that they wanted to include throughout the album.
Their unique post-rock sound and narrative are impressive. Late night, even at low volume, the sound that fills the room is very satisfying. It's a musical pleasure to feel."
"...Black Flak and the Nightmare Fighters closed the show and took us to a decidedly darker place, both sonically and visually, with a heavy dose of distortion and mood lighting...they brought about a drastic, though certainly not unwelcome, change of pace with an immersive musical experience, complete with cryptic samples, sound effects, and sirens. This is music fit for an apocalypse; music better lived-in for a time than merely listened to. Be sure to check out their debut album..."
