I got a show coming up Sept 1 at Silence in Guelph with the incredible post-classical guitarist Bilal Nasser. So honoured to be sharing the stage with Bilal for his album release tour. His last album ‘How Can We Say Nothing’ is a personal fave and gets heavy rotation ‘round the house. C’mon out!
A show poster with a light blue background. The main picture is of a blue flower and its roots and leaves growing up the middle and slightly to the right. To the right of the flower, in vertical text and block letters reads ‘Ever Martyr is a Universe Album Release Tour’. To the left of the flower are the artists playing - Bilal Nasser, M.Mucci and Pretty Math. Below in a beige box reads Live at Silence Guelph Ontario. September 1, 2026, 8pm. $15/PWYC. New Album on Constellation Records

Recently finished a side project where I simulated a stable 3-tier ‘ecosystem’ of plants, herbivores and carnivores in pygame. Herbivores eat plants and carnivores eat herbivores in stable phases, in line with Lotka Voterra equations, but with added spatiality. You can read about it on my GitHub
Screen cap of the simulation world. An isometric tile based grid with green (plants), blue(herbivores), red (carnivores) and grey (rocks)Screen cap of the phase plot chart of the simulation, showing the populations are stableThe populations graphed through time show the populations roughly follow Lotka Volterra cycles.

As a cartographer, this actually makes a lot of sense
Behold a square! A shape with four sides of equal length, with four right triangles. But it’s not the squares we’re used to…. It follows all the rules of being a square but has like a circular pie shape
