They give us nearly 40 minutes of soundscaping that is at times noisy, always eventful and with a kind of avant narrative structure that poeticizes and gives us an unworded story line for our ears.
This isn't pat-your-foot music. It unwinds in time and is of time, but it is not in metric time. Once you get used to that there are a great deal of exotic sound structures to take apart in your head, as you get a bit at a time and it evolves and convolutes about itself before your ears. There are long sustained sounds that make it all a soundscape. It is an original set of sounds well-paced. You have to hear it to get into its anatomy/structure, really. Words don't do it justice.
The whole thing is quite out there and quite good. Thank you again, oh Portuguese music-makers. Here's another goodie.
