Within the current U.S. sociopolitical context of rampant violence, increasing levels of racism and xenophobia in society and the rise of authoritarianism in schools, a new and fresh confluence of Maxine Greene and Paulo Freire's work revitalizes and expands the concept of radical hope. Their educational philosophies enable one to see beyond "what is" into more democratically just and humane worlds of "what might" be. This article focuses on ways that these two scholar-activists' key contributions converge to release a much needed melody that exposes exploitation and falsehood while inspiring wide awakeness, personal reflection, and directed action. Inspired by the metaphor of playing music on the blue guitar, it takes a "call and response" approach to examining these key ideas from the works of Greene and Freire that are parallel and complementary to each other. Sounds of Maxine Greene's (1995, 2001) and Freire's (1970, 1992) harmonic pairings of wide-awakeness and critical consciousness, aesthetic education and "reading the world," social imagination, and radical hope will resound anew, with particular attention paid to ways that both Greene and Freire define hope above and beyond passive and wishful thinking. The authors conclude by reframing radical hope as a "theory of change" (Tuck and Yang 2014) in which imagination can be understood as an insurgent praxis useful for destabilizing the contemporary global neoliberal order that is more concerned with creating workers and consumers than democratically minded citizens.
