For all who are interested in the traditional folk music of America, BlueRidgeMusic.org provides a searchable database by state, county, location, keyword, and date of all traditional music happenings in the Blue Ridge Mountains between North Carolina and Virginia. The Marshall Depot is listed as a venue, as are a few other gigs in and around Asheville.
The database is courtesy the Blue Ridge Institute and Museum at Ferrum College in Virginia, which also has some pretty cool Appalachian music material in its current online exhibit, “Deathly Lyrics: Songs of Virginia Tragedies.”
