'Blue Velvet' changed my life forever. It was like I'd always read Chaucer and suddenly discovered Charles Bukowski. It made me understand that there is poetry of sublime ecstasy and dark terror, and it spoke to a side of me that hadn't been reached before.

After a noticeable silence, he'd recently published a book of technically baffling poems, with line breaks so arbitrary and frequent as to be useless, arrhythmic. On the page they look like some of Charles Bukowski's skinny, chatty, muttering-stuttering antiverses. Impossibly, Mark's words make music, the faraway strains of an irresistible jazz. It's plain to any reader, within a few lines-well, go read the poems and see, Marcus Ahearn traffics with the ineffable. He makes the mind of the speaker present, in that here-and-now where the reader actually reads-that place. Such a rare thing. Samuel Beckett. Jean Follain, Ionesco-the composer Billy Strayhorn. Mark calls his process "psychic improvisation" and referred me to the painter Paul Klee; the term was Klee's. "You just get out a pen and a notebook and let your mind go long," he told me.
