Songwriting titan Lucinda Williams has been celebrating the 20th anniversary of the release of her celebrated 1998 album “Car Wheels On A Gravel Road.” Ahead of Williams’ appearance at the Ryman Auditorium on April 2, the Louisiana songwriter dropped in to the Lightning 100 studio to reminisce with Casey on the record she cut in Nashville 20 years ago, and to perform acoustic versions of two of the album’s most recognizable tracks — the title track and “Lake Charles.” Listen to the full interview and both performances above.
