VALLIS MORTIS is an experimental psychedelic music project created by Tristan Robert Lange.
Blending immersive sound design, cinematic progression, spoken word, progressive experimentation, existential atmosphere, and painterly psychedelia, VALLIS MORTIS explores altered states of perception through deeply conceptual sonic experiences. Each release inhabits its own symbolic and emotional terrain…from luminous transcendence to intimate confrontation with mortality…while remaining connected through a shared commitment to atmosphere, immersion, and philosophical depth.
Rather than functioning as traditional albums alone, VALLIS MORTIS releases are designed as experiential worlds: spaces where memory, consciousness, beauty, decay, transcendence, longing, fear, wonder, and transformation coexist within evolving psychedelic landscapes.
Influenced by progressive experimentation, ambient storytelling, gothic-adjacent aesthetics, visionary art, and immersive conceptual composition, VALLIS MORTIS invites listeners not merely to hear the music…but to enter it.
This is not background music.
This is passage.

The Case of the Missing Seasons 🕵️♂️
I almost forgot to announce it…but Seasons is finally here. A journey through spring, summer, autumn, and winter…through memory, joy, loss, and hope. Listen wherever you stream music, or on Bandcamp. After all…art is community. 🖤

Shifting Spring
A multimedia descent into memory, winter, rebirth, and surreal interior worlds. Shifting Spring blends music, poetry fragments, and psychedelic imagery into an evolving artistic mythology where melancholy and fragile hope coexist beneath melting snow and cosmic water.

Death Pact
Death Pact’s my first experiment blending original psychedelic music with my poetry. Featuring my piece “Visions of Death,” this track weaves words and sound into a hallucinatory descent. It’s the seed of my upcoming project Vallis Mortis, but released here under my own name to mark where the journey begins.
