Rico, read the damn article. It's good stuff.
Both artists have made it a point to use their artistic platforms to advance social causes. Macklemore's "Same Love" features an openly gay singer, Mary Lambert, and was explicitly tied to the Washington State referendum to legalize gay marriage. Another song, discusses just that. Brubeck repeatedly insisted on performing with integrated bands when he led them, including touring the U.S. South with his "classic quartet" featuring black bassist Eugene Wright, or his World War II Army band in a time of military segregation. He also teamed with Iola Brubeck and Louis Armstrong to create The Real Ambassadors, a jazz musical addressing the Civil Rights Movement and U.S. foreign relations. One song, "They Say I Look Like God," is a biting satirical commentary on racism. The irony here, of course, is that while both are often credited for progressive politics, they operated within genres deeply rooted in progressive social criticism.
