Situations, Sings is a collection of twelve formally distinct poems collaboratively written by Jack Collum and Lyn Hejinian. Since 1992, the poets have developed a repertoire of forms and procedures, all intended to extend the possibilities for intervention, play, and the unfolding of unforeseeable meaning. Both poets embrace collaborative authorship as a means of challenging aesthetic preconceptions, including their own. 
 
Jack Collom (1931-2017) taught ecology-poetics and oversaw Project Outreach at the Jack Kerouac School of Disembodied Poetics, where was resident faculty for over two decades. His books include Arguing with Something Plato Said, The Task, and Exchanges of Earth and Sky. He also worked extensively with the Teachers and Writers Collaborative in New York City and was twice awarded a National Endowment for the Arts Fellowship. Collom lived in Boulder, CO.

Lyn Hejinian is a poet, essayist, and translator. Published volumes of her writing include Writing Is an Aid to Memory, My Life, and The Language of Inquiry. From 1976 to 1984, Hejinian was the editor of Tuumba Press; she is currently the co-director of Atelos, a literary project commissioning and publishing cross-genre work by poets. In the fall of 2000, she was elected the sixty-sixth fellow of The Academy of American Poets. She teaches at the University of California, Berkeley.
 
Adventures in Poetry began publishing in 1968 as a mimeographed “little magazine,” and continued through 1976 with individual pamphlets, featuring work by Ted Berrigan, William Burroughs, Allen Ginsberg, Bernadette Mayer, Frank O’Hara, James Schuyler, John Ashbery, Anne Waldman, and many others. After a long hiatus, it began publishing books by established and new innovative writers that are available exclusively through Zephyr Press.
