Diorama is both a book of poems and a performance action by the poet Roco Cern, who guides the reader on a hallucinatory, spiraling journey through image, language, Mexican history, and soundscapes. As unrelentingly tactile as it is unapologetically cerebral, Roco Cern's new book asks that we relinquish control and submit to the poet's brutal lyricism, and to a new kind of order imposed like a penumbra between us and the waking world.
