Which is a shame, because that's exactly what Knut do. The mathcore bit, not any of the other stuff.
Earlier records were very mathcore - at times sounding like a hardcore band in a metallic drum clattering down some steps. Third album Terraformer saw them get a bit more groove on; all the insane timing changes, atomic drum fills and fretboard gymnastics were still present, but measured out with more thick slabs of dense riffing and atmospheric electronica, with vocals taking more of a back seat - almost a third of the record was completely instrumental. It was like Knut had become masters of their rage, controlling rather than being controlled by it.
Fuck cuckoo clocks. This is the best thing to ever come out of Switzerland.
Closely followed by Toblerones.
