Adam Steffey, Ron Stewart, John R. Bowman, Keith Garrett and Harold Nixon make up the new group “The Boxcars.” With collective stints with Alison Krauss & Union Station (Adam Steffey, John Bowman), J.D. Crowe & The New South (Ron Stewart, John Bowman, Harold Nixon), Blue Moon Rising (Keith Garrett and Harold Nixon), The Isaacs (John Bowman) and most recently The Dan Tyminski Band (Steffey and Stewart), this quintet starts out with an impressive rap sheet.
