With yet another episode Strings and company continue their deep dive into vintage bluegrass music, providing a veritable history lesson with each passing day. As with several of the past releases, Saturday’s installment finds Strings ceding center stage to his highly-qualified backing band.

Yet toward the end of the 3:33 minute video, Strings finds a place to insert some brief-but-potent playing.Watch Billy Strings perform “These Old Blues” for String The Halls.
