Candiru..do you mean Candiria? DIllinger writes most of their music on paper before they play it or test it out accordign to an interview with the guitarist. I hate DEP, except for a few songs and the Patton album it's basically noise. I like Meshuggah, though, and Candiria and I'd throw Cryptopsy in there too, even if they're more death/grind then their 'math-metal' contemporaries.
