*200 copies limited edition* In 2019, ‘porous structures’ was released, the first album by the quartet Machtelinckx/Badenhorst/Cools/Gouband. The album won the Klara for ‘Best Belgian Jazz CD’. In September 2024, ‘porous structures II’ will be released, a new album by a quartet led by Ruben Machtelinckx, this time in the company of Fredrik Rasten, Frederik Leroux and again Toma Gouband. What remains is the choice for acoustic and fragile sounds, comprehensible to the listener but with an underlying tension and complexity. New is the intertwining of acoustic guitars. While the first album played with silence, ‘Porous Sructures II’ plays with textures. The melodic voice is exchanged for a group sound in which individuals are barely distinguishable. The classic roles in an ensemble are abandoned: the three guitars weave a web and the percussion moves freely through it. The quartet plays a stubborn game of endless, subtle variations.
