Cluster Funk is a community music and arts festival to support local artists, musicians, vendors, and businesses by bringing the community together. Cluster Funk is a one-day event full of performance, laughter, and enjoyment. We have pulled together some of the tastiest food and beer vendors along with talented up-and-coming artists to match. And best of all, our event takes place in one of the most well-maintained public parks in Iowa, Jester Park.
