Felix Riebl

Composer & Creative Director, Spinifex Gum

Melbourne artist Felix Riebl is a man of many hats; award-winning artist, globe traverser, family-man, footy fanatic, leader, gardener, chef. He has found comfort in chaotic spaces, performing to sold-out stadiums across the world, and in small domestic moments whilst surrounded by family and friends.

Through his authenticity, Felix has built a career on his broad and colourful music palette – never being type-cast in to one music genre, yet somehow always finding an audience. Across his projects, The Cat Empire, Felix Riebl, and Spinifex Gum there is a thread that ties all three together and that’s a sense of community, collaboration, and respect for the craft.

In his most recent work, Felix celebrates the wonder and obscurities of life, by shining a light on the interplay of insular domestic moments and very extrovert overflowing international moments that present themselves, with joy and exuberance.
