Three-and-a-Quarter Days of Peace and Books: That’s the promise of the third annual Woodstock Writers’ Festival, occupying the village of Woodstock April 19 through the 22nd. The event gathers an impressive lineup of authors, who will hold forth with their advice and anecdotes to one and all. And you don’t have to be writers, or even wannabe writers, to enjoy the show. Readers can come face-to-face with their favorite book people. Poetry types can listen to the rhyme and rhythm of a handful of working poets. And music-lovers can hear, firsthand, what it takes to invent those lyrics that wrap us in melodic rhapsody and deposit us on the shores of delight.
