Not actual math rock, I don't want to get into a genre purist debate, but I mean math-esque i.e. mathy. They flirt with changing time signatures across instruments constantly in their music; not necessarily complicated ones, but multiple through each song. I guess this style is more common nowadays with 90% of bands writing straight up label music or their music is influenced by their label so much that they're pressured to pack their music with more dynamics.
