"They can't knock you out if you keep moving. [Even on the page.]" writes Joseph Rios in the Prologue of this exciting and unforgettable collection. And the collection's sparring partner is clear. Rios squares up with the poetic traditions in which this collection is being thrown into. Rios writes in the Prologue that "the progression of this art form has left some people behind." And the collection moves forward with an urgency, fearlessness, confidence - 16 Rounds! - throwing combinations of lyric, narrative, and playwriting to honor the overlooked "sound, rhythm, cadence, word choice, simile, metaphor, etc." of his friends, brothers, and cousins. However, Rios doesn't write as himself. He gives us Josepho, an impersonation of Rios's grand imagination. And if a reader can't keep up with his dance, Rios says: "put the book down and go get lost in IKEA." Shadowboxing: Poems & Impersonations is doing something worth celebrating - simply bringing the poetic traditions into a new arena - Rios's backyard. After reading this collection, I'm proud to be a poet in the long, unsung lineage of Latinx poetics. Being a fan of the Rocky films, and seeing how the collection is organized around the films' knockout one-liners, well that brings me so much joy, too! A must read.
