Bob Crawford has been handling bass, violin, and backing vocals for the Avett Brothers since essentially the beginning of the band in 2001. Beyond his musical interests, he’s also a huge history buff, which has led to a different creative pursuit: He just launched a new six-part podcast about John Quincy Adams, the sixth president of the United States. Titled Founding Son: John Quincy’s America, it features the voices of Nick Offerman and Patrick Warburton (David Puddy from Seinfeld) as well as Crawford’s bandmate Scott Avett.
