For most of this century, Big Car Collaborative in Indianapolis has been not only the biggest force for redefining Social Practice Art, but they have also been extremely effective in practical terms of bringing parts of Indianapolis back to life, and reemerging these areas in a better way. Married couple Jim Walker and Shauta Marsh are the brains, the brawn, the creative and emotional forces that have made this work. In 2015 London’s Guardian presented them as an example of how gentrification can work, and be sensitive and aware of who lives in these neighborhoods and giving them a better place to live. Big Car Collaborative has brought in affordable housing, the Tube Factory art gallery, Listen Hear an ambitious sound art program and an FM radio station. These are just a few examples of what they have done. They have secured major funding from grants and donors. They are models of how to make a city a better place.
