"This is a much-needed book. Musical Christian responses to the climate emergency are immensely varied and astonishingly creative, including musicking in well known formats and innovations in sonic worlds that bring the human and other-than-human sound worlds together. The debates are carefully and clearly set out with remarkable respect for diverse theological and musical positions. Themes of coalition, pragmatism, creativity, boundary transcendence, community and relationship are drawn from musical, theological, spiritual, liturgical and interview data. Paradoxes and uncertainties are honestly addressed. This is an excellent and inspirational book that is an essential read for anyone concerned with Christian ecology."
