Main is back in grand form... After finalising his Firmanent CD's it's been a bit quiet around Robert Hampson. Although very busy with other projects as Comae (with Janek Schaefer), Chasm (Fatcat), his main output has been a bit low. Tau shows the first full album in years from a talent whom showed us the way to turn guitars into ambient. His unique way of concrete sounds and manipulating these into something of his own has always been his identity. Tau is no more or less a classic mover for quiet, threatening soundscapes with lots of attention for details. Details who are there to demand your attention. There is no way you can put this on as background music. The layers of overtones and quiet climaxes are very demanding for ears and brains.
