the SEED project


An ongoing collaboration (often adopting new names and taking new trajectories) between AT practitioners, dance-artist Georgia Paizi & musician Thodoris Ziarkas, inspired by the poetic literalism of the human body.

Mapping the overlapping landscapes of movement & music improvisation, the SEED sessions involve improvisation practice (guided through anatomical imagery and AT principles) hands-on work in partners, and scores for responsive choreography.

Bonnendis is a London-based trio featuring the raw sounds of the Greek islands with the iconic askamandoura (bagpipes), lyra and laouto. Bonnendis navigates from island to island, playing traditional tunes as you would hear them back home: genuine, powerful and uplifting.

The trio improvises on the crossroad between noise and melody. Using traditional instruments of jazz (Ziarkas, Chytiris) with a unique minimalistic approach as well as the electronics (Stamou), the musicians are exploring the nature and the limits of their instruments to produce sounds that are familiar but also unanticipated. Ethereal sounds of undetermined nature alternate with melodic patterns influenced by folk music but also jazz and electronic music.

...unites a collective of musicians around the idea of cross-pollination. Their eclectic compositions – though rooted in jazz – explore a plethora of stylistic influences, geographic confluences and mood-swings.

This is a newly formed project by Tasos Stamou (saz & bouzouki) and Thodoris Ziarkas (blues guitar).

The duo explores the borders of improvisation in the context of traditional music, especially focused in the musical heritage of Greek Rembetiko and Oriental music.


The musicians both interpret this musical tradition in their own special way; exploring the possibilities of this music existing and evolving into a contemporary context.

Stamou and Ziarkas, besides curating and running ‘Clapton Sessions’, are both performers of improvised music.
