In the center of Concord [1], the Colonial Inn (48 Monument Sq., 978/369-9200, www.concordscolonialinn.com [2], no cover) features nightly live music, including jazz, rock, and acoustic folk.
The Festival of Authors (late Oct.–early Nov.) keeps Concord’s literary traditions alive with big-name authors in a two-week-long festival every year. In addition to book readings, the festival usually includes sessions on literary history and how-to advice for writers.
