Trigram for Earth, by Flora Yin Wong, is inspired by traditional eight-sided Pakua mirrors and the trigrams inscribed on each of their edges. The function of the mirrors is to show the nature of reality as being composed of mutually opposing forces and modulate them. Here, energies seem to be manipulated to guide and direct our listening, lost in a maze of sound, diffracted to the point of merging with the artist's own listening, through her memories, her obsessions, the fragments she carries within her. Flora Yin Wong invites us to embark on a multi-faceted investigation of sound, a journey through the meanders of liberated sonic forces, an auscultation of her own listening and a portal, at last, ajar to a fragmented and forever mysterious inner world.In his work '50 frequency and amplitude modulated sine waves describing a landscape,' Sébastien Roux applies his approach to algorithmic composition to the observation of the natural world, bringing the sound of the sea and the song of birds into the electronic domain, transmuting them into each other through a slow process of gradual modulation. Exploring the abstract space of pure sounds between two naturalistic tableaux, Sébastien Roux offers us a fascinating meditation on the world of synthesis, revealing, with an economy of means and great formal elegance, the magic of sonic simulacrum (deepl propose simulacra, mais là je suis pas assez calé_) and the strange beauty of the artificial, in a gesture that is ultimately as poetic as it is musical.
