Are you familiar with Death? If not, you should be. This mid 70's band of three Detroit brothers remained largely undiscovered until 2009 when Drag City released the album ...For The Whole World To See. Their story is amazing and I highly recommend the New York Times article that I have linked below. Enjoy.
