13 Ensemble is a 13-member musical collective led by Ester F. Mata as composer, performer, and conductor. The ensemble merges hypnotic minimalism, cinematic soundscapes, and a highly interactive, chord-less approach. While Ester’s compositions provide a structured framework, musicians actively shape lines, react to cues, and interact with electronic elements, creating a sound that is immersive, spontaneous, and collaborative.

The repertoire blends fully notated material with free improvisation, raw textures, cues, and playful experimentation. Through extensive rehearsal and ongoing dialogue, the ensemble cultivates trust, flexibility, and a shared musical language, resulting in performances that are dynamic, engaging, and unpredictable. Electronics are often used as a subtle layer, incorporating recorded speech and sounds from daily life to add expressive and conceptual depth to the music.

13 Ensemble reflects Ester F. Mata’s vision of music as a collective practice, emphasising collaboration, the shifting of traditional ensemble roles, and the intersection of composition and improvisation, producing a distinctive and evolving contemporary sound.
