In The grass is greener when the sun is yellow, poets Sarah Rosenthal and Valerie Witte engage with the work of dancer-choreographers Simone Forti and Yvonne Rainer. Through research into these innovative women's dances, ideas, and lives, Rosenthal and Witte use language from and about the choreographers to create a series of co-written sonnets that are interwoven with letters between the two poets. These letters describe the process of composing the poems and branch into discussions of dance, poetics, gender, transgression, the unfolding disaster of the current political scene, and much else, in the associative weave that epistolary form enacts. Together, the poems and letters construct an environment of reflection, intimacy, and vulnerability, one that is both challenging and invitational.
