Blue King Brown is an Australian urban roots ensemble formed in 2003 in Byron Bay by mainstays Nattali Rize and Carlo Santone.

They have toured nationally and internationally; and supported concerts by Santana, Michael Franti & Spearhead, Damian Marley, the John Butler Trio, the Cat Empire, Silverchair, Dispatch and Powderfinger.

[14] AllMusic's Steve Leggett opined that it "finds the band in full passionate flight, delivering contemporary reggae that sounds urgent, necessary, and vital" with the group "quickly becoming a force on the international jam band urban roots scene, mixing reggae with Afro-beat and Latin rhythms and layering them beneath lyrics that cry out for positive social change.

"[14] In January 2015 Blue King Brown toured Australia to promote Born Free with the line up of Cope, Fredes, Persico, Rize, Rodriques, Lea and Petra, and Santone.

[15] Bobby Goudie of The Clothesline caught their performance at The Gov, "They get their audience grooving and absorbed with their up-beat tunes and messages of hope, peace and standing up to oppression around the world... [and are] a skilled, experienced band that has been spreading their ideas and conscious music for over 10 years.
