What shape is your rock? Is it a soft indie radio dial like circle or a complex math rock dodecahedron? Perhaps your audio geometry angles towards hip-hop rap-azoids or sharp, metal-edged punk rock triangles. Expect the Shape of Rock to deliver a heavy dose of Milwaukee beer-can blues, Wisconsin sharp cheddar-shaped jazz, and Northwoods pine tree-shaped country. Whatever your preference, don’t be a square – tune in from 6 to 9 a.m. every Tuesday morning.
