Born and raised in Brandon, Manitoba, Canada, Karl has called Paris his home for over twenty years. As one of the most in-demand drummers in France, Karl completes his musical identity with his songwriting which Telerama called “an enchanting crossroads between cosmic pop and hypnotic jazz”.

He has recorded six other albums and an EP, entirely comprised of his own original music : Liberating Vines (2004) ; Thinking in Colours (2009) ; Streaming (2010) featuring Sienna Dahlen; The Halfway Tree (2012) ; Midseason (2016) featuring Denzal Sinclaire ; On the Brighter Side (2018) featuring Cynthia Abraham.

In 2016 Karl co-founded the Shed Music collective with Christophe Panzani, Pierre Perchaud and Tony Paeleman - members of his close-knit musical family who also form the band, The Watershed.
