How it works

01 — Recording — Preparing for the workshop, I walk the festival or venue grounds recording the plants themselves, using a contact microphone attached directly to the stem, capturing their vibroscape. Participants may take part in this too.

02 — Editing — The recordings are filtered and shaped, ready to play at the workshop. This preparation takes a couple of hours.

03 — Listening together — At the workshop, I play the plant recordings for the group, naming each plant as we hear it. This part is quiet and meditative — a shared act of attention.

04 — Playing together — Then the group splits into trios. Each trio chooses which plant sounds they want to play with, and I loop those sounds live, turning them into rhythmic patterns to improvise over.

05 — Improvising — The trios jam together while I move between groups, passing ideas from one to another.

06 — Concert or release — The improvisation becomes the basis for a new instrumental piece — either performed live at the end of the workshop, or, as at Positive Trace Festival 2026, developed into a recorded release (hear a sample in the video above). I play clarinet, echoing and imitating the plant sounds, and other musicians can join depending on the context and time available.

“Wow, I had no idea a plant could make these sounds?!”
