Quantum Requiem is a sonic odyssey through the collapsing boundaries between organic life and synthetic consciousness.
THE DEONISOS merges the brutality of modern metal with the transcendence of cosmic ambience — creating a digital requiem for a universe on the verge of rebirth.

Every track feels like a fragment of a dying star transmitted through broken machinery: glitch-laden riffs, shimmering ambient layers, cinematic choirs, and the haunting pulse of data decaying into noise. This is where deathcore meets space opera, and djent evolves into digital mythology.

With pristine production, high-fidelity mastering, and futuristic sound design, Quantum Requiem stands as both a lament and an awakening — a requiem for the known world and a hymn for what comes after.

My interpretation of what would be Ranger's (Quake Champions) theme song! I was kind of envisioning how fighting game characters have their tracks that play while I made this. With Ranger originating from Quake 1, I knew it's soundtrack needed a heavy presence in this one. I threw in references to the tracks Quake Theme, Aftermath, Hall of Souls, and Life. Going with the sort of Gothic theme that Q1 had, throwing in a little pipe organ would hurt either as the Volkerh mapset utilizes it as well. 

A good chunk of the Q1 OST is in the key of D, and deviating from that ended up sound wrong, so in order to get my guitars as low as I wanted them to... I didn't use them. The heavy parts are actually a bass guitar using electric guitar processing. In my mind, this track is my impression of Sonic Mayhem and Mick Gordon interpreting Trent Reznor's classic Quake OST.

Ranger has a tragic story, as he was ripped from his family and tossed into the nightmarish world of Quake from which he can't seem to awaken. I wanted to reflect this in the somber tone of the chorus in this track (and inadvertently ended up giving a subtle nod to the Max Payne theme). Part of me wanted this song to end on a looping fade out to sort of reflect him being trapped in hell.
