John Brown's Body is an American reggae band from Boston, Massachusetts and Ithaca, New York, that tours the world performing what the group calls “Future Roots Music”. The sound is rooted in reggae rhythms and blended with a variety of other styles including dub, electronic, funk, ska, hip-hop, and dubstep.

The band’s sound has been described by the New York Daily News as being "more Massive Attack than Marley" and by the Village Voice "reverent and revolutionary at the same time.”
