If Texturalis was a real word it might have something to do with the density or porosity of organic compounds.
In the case of Machinefabriek's Texturalis, the word fits the sounds on this album. Sounds indeed, not songs. Anyone familiar with Machinefabriek knows his interest in anything crackling, fizzling and buzzing. For Texturalis, Machinefabriek choose to work on just that; not to be bothered with creating elaborate compositions, but to focus on creating intriguing textures. This resulted in 18 two-minute vignettes. Each of these could be a glimpse of a continuous sound environment.
