*100 copies limited edition* Low Tide, Hi Grypus! is the new live-iteration of JC Leisure as JC Leisure Group. Documenting an encounter and a communication between human improvisers and atlantic grey seals. The record presents responsive improvisation as a form of cross-species collaboration.

The project began on Porthdinllaen, Wales, where Leisure recorded seal vocalisations from a local colony at low tide. Back in their Liverpool studio, Leisure developed a performance system that translates human musical gestures - pitch, timbre, rhythm, density, presence - into triggers for these seal expressions. The resulting system is dual-active, as in it simultaneously acts and is acted upon in the horizontal instance. It creates a new-music non-linear threshold that cannot be replicated.

Low Tide, Hi Grypus! was recorded live at 1210 Berlin and captures one instance of this concept. Local improvisers were invited to encounter the performance system. Recorded in one take, pedal-steel, woodwinds, strings, piano, organ, and electronics gradually learn to listen and respond to the marine voices. This interspecific group moves from intimate duets (that's human, seal) into full ensemble works (humans, seals) over the course of one night.

Rather than treating field recordings as static material, the extensive seal archive functions as an active collaborator: shaping form, pacing, and interaction in real-time. Now that’s marine biology meets human communication! JC Leisure has previously released work on Sun Ark, Warm Winters Ltd, Not Not Fun and collaboratively with Dialect as Raft of Trash. He has composed a radio play commissioned and broadcast by BBC Radio.
