The Brother Brothers are rooted in sibling harmony provided by twin brothers Adam and David Moss. Adam Moss would prefer if you didn't get really weird about twin stuff: “We sometimes find being twins a barrier to conversing and getting to know people quickly. It’s an easy thing for people to fixate on," he says. Truthfully there is PLENTY to discuss with Adam, who plays several instruments, but started on the violin. His focus was on classical, but he studied Klezmer and sometimes incorporates it into his music. Adam talks about what it means to include his Jewish heritage into his songs. While attending the University of Illinois in Urbana-Champaign, Adam and David started to realize that the classical world was not for them. Adam joined a bluegrass band and eventually moved to Austin, Texas to be closer to the community that surrounded the Kerrville Folk Fest, which was an integral part in his development as a roots player. David also moved to Austin, but the brothers didn't start their project together until they relocated to Brooklyn. There, they discovered they were ready, musically and personally ready, to be in a band together.

Originally, The Brother Brothers did not write together, but this is something that has changed with their new record, Calle Lily. Adam talks about writing with David has impacted his process. The album is filled with comfort, warm sincerity and an earnestness that comes off in a very cool and authentic way. I'd definitely describe Adam's temperament as such and get his opinion on that observation as well. If we're not gonna talk about twin stuff, the second most awkward thing you could discuss is how you are as cool as you are. Adam pulls it off great.
