Free Radicals is both Nick Cooper's revolving-door ensemble that at any given moment could be playing free jazz or Latin funk, and also Cooper's ongoing testimonial to how much he digs being a member of the Houston music community. He has so much experience at this point that he has very much become a one-man hub of that community. In 2012, Cooper brought that same kind of musical civic pride to the Radicals' first album in several years, The Freedom Fence, and then in July watched it win a well-deserved Houston Press Music Award for Local Album of the Year. The group's weekly jam, wherever it may be, is a true local-music institution. For a while it's been at AvantGarden, a local-music institution of its own, and follows David Dove's avant-music showcase They, Who Sound — still another.
