Built upon the sturdy foundation of Scott and Seth Avett’s harmonies, banjo and guitar, with a healthy contribution from Bob Crawford on standup bass and Joe Kwon on cello, The Avett Brothers have evolved from local sensations in their home state of North Carolina to the kind of nationally-beloved duo that is nominated for Grammys and gets an HBO documentary made about them.
Coming to prominence during the Americana boom of the late aughts, but with a lot more meat on their bones than acts like Mumford & Sons or The Lumineers, the band has a deep and varied discography, including tender piano ballads such as “I and Love and You,” plaintive acoustic laments like “Murder in the City,” and more up-tempo folk-rockers like “Paranoia in B Flat Major.” The band’s reputation as a live act that’s not to be missed has certainly aided their rise. They’ve released four live albums that do an excellent job capturing their energetic, singalong-heavy concerts, and though their music has skewed a bit more mainstream in recent years, their live shows remain a transcendent mix of seamless harmonies, rollicking instrumentation and the devotion of a fervent fan base.
