Louisville resident Nathan Salsburg dedicates much of his time to good works. He produces a radio program called Root Hog or Die for East Village Radio, and he works for the Alan Lomax Archive / Association for Cultural Equity as an archivist and producer, overseeing the production of CDs and online offerings. He also runs the Drag City-distributed imprint Twos & Fews, which has released a handful of meticulously curated and produced recordings from the American south and Morocco. This fall the label issued its fourth title, a vinyl-only anthology plucked from the Lomax Archives by Scottish folk-rock singer Alasdair Roberts: Whaur the Pig Gaed on the Spree.
