For more than 20 years, the Madison-based group Natty Nation has purely and fearlessly followed its inner artistic continuum. Along the way, Natty Nation has burst through genres while retaining a distinct roots reggae core. Through it all—whether it’s onstage conducting its shamanistic live show, or in the studio pushing the scope of its musicality while honing its sharp songcraft—Natty Nation has remained dedicated to one mission: spreading light. See Natty Nation perform at the Memorial Union Terrace Aug. 18. This free performance is presented by the Wisconsin Union Directorate Music Committee with support provided by the UW Credit Union.
