The Avett Brothers' 2007 release "Emotionalism" is the album that caught the attention of legendary producer Rick Rubin and got him to sign the band to their first major studio. "Emotionalism" also was their first album to crack the charts. Full of new Folk, Blues and Bluegrass riffs for a modern world, it is a lively take on everything from romance to paranoia. Of course, they still kick in some solid Rock 'N' Roll for good measure.
