Marina Katsarou is a Greek vocalist and creative collaborator whose work spans experimental, electro-acoustic, and conceptual sound environments. She contributes voice and text to projects that explore the sonic identities of urban and artistic landscapes, most recently appearing with the Thessaloniki-based ensemble Eventless Plot on their Unlearning Noise release, where her vocal presence frames and animates reflections on the textures and meanings of city soundscapes.

Eva Matsigou (Εύα Ματσίγκου) is a Greek flutist, musician, musicologist, and sound researcher active in the experimental and electroacoustic music scenes. Based in Greece, she is known for her work with the Thessaloniki trio Eventless Plot, appearing as a guest musician on several releases including Parallel Worlds and Anisixia, where her flute contributions expand the group's textural and spatial approach to sound. Alongside Nefeli Sani, Matsigou co-founded the duo I Broke the Vase in 2018, a project centered on listening-based performance, free improvisation, and composition using instruments, voice, objects, electronics, and field recordings, often informed by feminist artistic perspectives. Her practice spans experimental, minimalist, contemporary, and electroacoustic improvisation, extending into video performance, sound research, and curatorial work focused on amplifying women's voices in electronic and experimental music.

"Eventless Plot borrows elements from different genres and aesthetics to build their own hybrid of sound. Formed in Thessaloniki in 2002 by Vasilis Liolios, Aris Giatas and Yiannis Tsirikoglou, the trio exhibits great attention to sonic details expressed in different forms of experimentalism. They use a variety of instruments, analog sources, field recordings and Max/MSP patches."
