Let me start by saying that Art rock is sadly not represented enough in math rock these days.
An Anderson perfectly bridge discordant guitars and post-punk sensibilities into the herky jerk rhythms we crave.
The point of failure in most art rock is cranking the guitar knob to "annoyingly abrasive".
An Anderson balance some pretty inspired riffage with pop undertones to avoid this problem altogether. The post-punk vibe going on always lends itself well to labyrinthine structures and so ends the other piece to this pretty incredible pie.
