On Spaces, Jos Smolders spends over two hours immersing listeners into the sound worlds of museums. While a quotidian capturing of such institutions would be an interesting endeavor in and of itself, Smolders instead uses their curious atmospheres as a mere starting point; what often begins as a typical field recording soon evolves into a larger musical event that finds him taking on a more pronounced role in the proceedings. As such, it would be dishonest to purport that the album gives a good sense of the exact nature of these locations, and it doesn't seem to be Smolders's goal either. His active participation in these compositions finds these subjective interpretations to be a window unto his experiences: a personal but valid approximation of what these spaces are actually like.
