Free Radicals is an American band from Houston, Texas, that combines elements of several genres: jazz, funk, ska, reggae, hip-hop, African, and Indian music.

[3] On recordings — The Rising Tide Sinks All (1998), Our Lady of Eternal Sunny Delights (2000), Aerial Bombardment (2004), and The Freedom Fence (2012)[4] — Free Radicals invites a group of 50 or more musicians and vocalists into the studio.

[3] In 2000, The New Yorker wrote, "The horn-heavy, continually evolving collective Free Radicals produces a wildly eclectic fusion that has as many influences as there are items in the Houston, Texas, pawnshop in which they honed their sound during all-night jam sessions.

"[5] In 2010, Dawn wrote that the artwork and message about underwater oil-leaks, oil-wars, and bank-crashes on the band's first CD was like a "premonition waiting to become true.

"[6] Free Radicals frequent collaborators and guest musicians include Al Pagliuso, Dan Cooper, Harry Sheppard, Gloria Edwards, Nelson Mills III, Subhendu Chakraborty, and Karina Nistal.
