John welcomes Avett Brothers bassist Bob Crawford to discuss his new book, “America’s Founding Son: John Quincy Adams, From President to Political Maverick.” Crawford explains how JQA, after a mediocre single term in the Oval Office, blossomed into America’s “most extraordinary ex-president” and arguably its greatest all-around public servant; the evolution of his popular history podcast The Road to Now; and the genesis of the recent, seemingly unlikely collab between The Avett Brothers and Faith No More frontman Mike Patton.
