Portals

Produced entirely from sounds recorded in the Amazon rainforest in Brazil and Colombia, Portals evokes the hidden world of sounds that lie beyond our perception.
Whether concealed in ultra-sonic frequency registers or in the depths of the aquatic medium, these sounds bear witness to an unsuspected and teeming animal activity. Insects, frogs, bats and freshwater dolphins move about, hiding from our eyes and ears. Revealing this palette of sounds, in particular through transposition, and placing it back in the realm of the audible, Jana Irmert invites and guides us on a fascinating exploration of an unsuspected, speculative and non-human world of sound, which she exposes and recomposes in a way that is both respectful and personal, accompanying this teeming and fascinating sound material in a musical gesture of great clarity.
Portals is an attempt to access the evocative power of an Amazonian forest on the brink of catastrophe, through a decentring of the listening experience delicately composed by Jana Irmert. (François Bonnet)

"Portals arrives out of the forests and riverbeds of the Amazon - not the postcard version, but the unlit, ultrasonic, insect-ruled dimension where sound shivers beyond human reach. Irmert has spent the last years developing her practice around field recordings, spectral reshaping and quiet, severe patience; here she pushes that approach into something like an X-ray of a biome. Her hydrophone and ultrasonic captures are not just transposed into audibility but re-imagined, rearranged, cradled into a single slow-unfolding environment where every chirrup, throb, and submerged pulse feels at once documentary and dreamlike.
There’s a sense - whispered rather than shouted - that this forest is vanishing as we listen. Not in a sentimental way, but in the eerie, factual manner of a world eroding under its own pressure. The “portal” she constructs is therefore double: an opening into an unseen ecological vastness, and a reminder that such openings may soon seal shut. Yet the piece never collapses into gloom. Irmert’s sound design has a clarity that feels almost ceremonial, a sort of sonic lantern held up to illuminate the creatures whose frequencies we normally miss. It’s patient, lucid, and strangely welcoming, even as it brushes against the edge of catastrophe.
"Portals / Rope" is a study in listening as recalibration. A reminder that the world is louder, stranger, and far more intricate than our everyday ears assume. And, in its quiet way, it’s also deeply moving - the kind of record that opens a door, leaves it ajar, and trusts you to decide whether to step through."
