10+ years later, I still go back to it. It's a fine piece of ethereal noise pop. I tracked down the rest of their albums. They are all good in their own way, but this is my favorite.
When I read the reviews and comparables for SIANspheric, I find it interesting that the bands mentioned do little for me: Low, Swervedriver, Bethany Curve, Windy & Carl...etc. It's not that I dislike those bands; it is more like I choose never to listen to them because they don't really play anything that interests me...but SIANspheric does.
Who knows why? I try not to care too much, and just let my ears point wherever.
