KDHX is a local "alternative" radio station. Lots of music, leaning toward folk, international, Latin and world, singer-songwriters and news about the local arts scene. It's not entirely justified, but it has a reputation of appealing to aging hippies.
They had a street festival in front of the station's building. Bands, food trucks, exhibits promoting social and environmental and social causes. I came there from the Annie Malone parade and my back didn't let me stay long. Still, there was good people watching.
