Tamar Yoseloff’s A Formula for Night: New and Selected Poems from Seren includes dazzling new work as well as selections from her print collections and pieces from collaborations with artists. The title poem was commissioned by the Hayward Gallery for their 2013 exhibition Light Show and is based on an installation by the Welsh artist Cerith Wyn Evans – a meditation on the space between heaven and earth. The poems in this collection are also concerned with heavenly presences, as well as evil spirits, explorations of light and dark. As well as the title piece, many other poems are informed by the work of visual artists, such as David Harker, Alison Gill, Susan Collis and Fred Sandback. The book also includes some poems from Formerly, a chapbook published in 2012 which included photographs by Vici MacDonald. The Formerly project was shortlisted for the 2012 Ted Hughes Award for New Work in Poetry.
