From his home in Louisville, Kentucky, we talk to guitarist and music historian Nathan Salsburg. By our count, Salsburg has released two of the best instrumental acoustic guitar albums of 2011: Avos, a duet record with James Elkington, and a solo album entitled Affirmed.  We chat with Salsburg about both records, the guitars he used on these projects and his unique day job, working for the Alan Lomax Archives. We also discuss some of his favorite guitar players, including Nic Jones (featured in the Fretboard Journal #21) and E.C. Ball (a huge influence on luthier/player Wayne Henderson). It's an interesting half-hour chat with one of the guitar world's rising stars.
