On the page and off, James Dickey (1923-1997) was a maximalist. His roomy, loquacious poems spill down the page in a waterfall style and in a voice he called “country surrealism.” It makes sense that he called some of these poems “walls of words,” similar to the record producer Phil Spector’s echoing “wall of sound.” Dickey’s music, rougher and weirder than Mr. Spector’s, was similarly packed with reverb.
