The two accordions, also transformed into speakers, are here vibrating surfaces traversed by broken lines, shrieks, and pulsed motifs that fragment then reorganize. The sound jolts, doubles, diffracts in the diffusion space, creating a fractal, luminous texture, always in motion. From the groove traced by the duo emerges a myriad of doubles created by electronics, in a rhythmic urgency where each attack seems to contain an infinity of repercussions.
