Paddle Steamer Waverley, sailing on the Thames estuary by Shornemead Fort east of Gravesend. Mix of hydrophones and above-water microphones, with the wind carrying the sound of the paddles above the water only for a few seconds

PS Waverley on the Thames by Shornemead Fort

Analog-tech wrapped in adult lullabies — Emil Slablife delivers what feels like a twilight oratorio of the absurd. It's electro that splits your seams.

On stage with his machines, he launches into a relentless live set, offering the audience no pause for breath.

Hailing from Biel, he has just joined the LCD83 family, alongside Serotonine, Trash Mantra, and Schade.

His debut single, “Whales”, sets the tone for a powerful series of analog techno tracks bound to ignite dancefloors.

Two periwinkles munching on a seaweed stipe. Their varying tempos and soft crunch created an entrancing rhythm. 

Extract from a 20m recording by Julie Brook's tidal sculpture Tide Line along the Fife coastline, created as part of the national coastal arts festival Beach of Dreams.

Deep Ice is a unique sound collection capturing the organic power and delicate beauty of ice in motion.
Recorded with precision on frozen lakes, this library offers an immersive palette of crystalline cracks, deep impacts, and pure debris.
You will find:
Under-ice recordings with an Aquarian H2d hydrophone: deep cracks and resonant fractures

Surface recordings in XY stereo with Schoeps CCM4: sharp impacts, hits, textures, cracks, and debris

These sounds are ideal for film and series sound design, video games, and musical creation.
Each recording has been carefully cleaned and formatted to UCS standards.

Musician and field recordist Action Pyramid finds magic in the everyday on Mardle, a compelling and confounding suite of hydrophone compositions revealing the sonic 24-hour cycle of the UK’s freshwater ponds.

Rooted in Jack Greenhalgh’s sonic research on pond biodiversity, Mardle brings to the surface the delicate sounds of aquatic insect stridulations, plant respiration and photosynthesis - an ecology of otherworldly rhythms and alien hyper-sounds that feel more like early synth experiments than biological processes.

As Greenhalgh explains, “It's so exciting that we've discovered the woodland bird song dawn chorus equivalent for ponds, in the form of nocturnal aquatic insect choruses at night-time, and the whining of aquatic plants as they photosynthesise like busy factories during the midday sun.”

In doing so, Mardle takes the daily cycle as its compositional cue. Beginning above water, the listener is plunged into a “strange and mysterious” world, peaking in the frenzied, pulsing activity of midday and midnight, before the calm of the early morning rain returns above. Inspired by Jana Winderen’s creative underwater soundscapes, the result is quietly breath-taking.

“To actually consider the living presence of plants with direct sonic evidence is quite profound,” Action Pyramid says. “It's such an evocative way to capture people's attention and highlight these fragile and maligned habitats. There have definitely been moments where I think I can’t believe I'm listening to this.”

Accompanied by detailed liner notes that explain Greenhalgh’s findings and the implications of acoustic ecology in freshwater monitoring, Mardle is a perspective-shifting, mind-expanding missive from the shallows of one the most familiar and overlooked ecologies on Earth.
