"Bootleggers and Baptists" are not a duo that is categorizable. This is illustrated in the socio-political model, (Bootleggers and Baptists), from which the name is based. Basically, two guys, who's positions are completely opposing, desire the same goal- but for their respective reasons. The Bootlegger wants prohibition because it inflates the price of his product, and The Baptist because he thinks those ought not to sip the "Demon-Drink" anyhow. The politician will then play both perspectives and pass prohibition, instead of doing what is in the general population's interest.
Aaron Buckingham (drums & keys), and Josh Harrell (guitar & vocals), are cousins; they have been playing music together since they were children. One is not a Bootlegger, and one is not a Baptist, because then who would be the Politician? Their Instruments? They are however, two incredibly different people relating through music- with a style that sounds a lot like the adjective "rootsy".
