Jack William McAllister, known professionally as Willaris. K, is an Australian electronic music producer.

In his career he has created thumping official remixes for Grammy-nominated artists Flume and RÜFÜS DU SOL, and dipped his toe in the world of film and TV, scoring the trailer for HBO series ‘This Is Love Life’ and working on a new US TV series alongside Alex Somers (Sigur Ros producer, Black Mirror composer).

His 2022 releases ‘Slow Down’ and ‘Melt’ marked the dawn of a new era for the rising producer, as he returned to live stages around the world.
