Everything starts with the idea that the place you live in is beautiful. Then you don’t deface it.

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

Point cloud scans of trees on the cottage property. Thinking I’ll make it a print and frame / hang one in the cottage.
A 3x3 grid of LiDAR point clouds of individual trees titled “Bayside Tree Scans - 2021”. The point clouds are a gradient of red (highest) to blue (lowest), showing their rough silhouettes and heights
