The Avett Brothers are a non-traditional bluegrass band that originated in Concord, North Carolina. The band is made up of two brothers, Seth Avett and Scott Avett who play the guitar and banjo, respectively, and Bob Crawford, who plays the stand-up bass. They are often joined on tour by cellist Joe Kwon.
