The meticulous and magnificently creative mind of wind player and composer Jean Derome used a 2010 Sudoko puzzle as a guide for his "Sudoko Pour Pygmees", presented alongside "7 Dances (for 15)" and "5 Thoughts (for hard rubber)", performed by an octet of Montreal mainstays including Pierre Tanguay, Pierre Cartier, Guido Del Fabbro, Bernard Falaise, &c.

Canadian guitarist Rene Lussier formed this quintette in 2016, with Julie Houle on tuba & euphonium, Luzio Altobelli on accordion, and drummers Marton Maderspach & Robbie Kuster, to play the intricate and lyrical pieces he developed, where up to five parts are overlaid at any given time, though the listener only hears the wonderful interplay and exultation of the resulting music.
