Firstly, I should say this is a subtle work which requires repeated listenings.
I'd say there is an element of metallic-type sounds, but overall the album isn't unbalanced tonally - there's a lot more going on in the spectrum as well as the sounds in the upper frequency range. Perhaps only on Track 6 is the balance veered a tad far towards the high-end (for my particular preferences) where the piano is featured alongside a static like sound (which has an almost has a breathy quality) which is a tad 'forward'. Interestingly, the album starts with a distinctly HF free intro.
There are subtle compositional and structural elements which prevail throughout the album and it is spatially interesting too - again in a subtle manner. Sometimes I find 'wild pannings' to be a bit distracting unless there is something to offset these shifts against - more 'centred' sounds.
I think an artist should stick to their guns, so to speak. If they decide to create a work with a particular sound signature, thats their choice. Like every other creative decision it won't be the same for everyone, that's what happens when any artist releases a work - you open yourself for reactions, positive and negative.
