The Avett Brothers is an American folk-rock band that originated in Concord, North Carolina. Two brothers, Seth Avett and Scott Avett, formed the group in 2000 after the breakup of the former rock band, Nemo, adding a third member, Bob Crawford. Subsequently, they have been joined by cellist Joe Kwon. The Avett Brothers combine old-time country, bluegrass, punk, pop melodies, folk, rock and roll, honky tonk and ragtime to produce a sound described by the Washington Post as "post civil-war modern rock", or by other reviewers as "grungegrass".
