Something incredible has been happening in the music scene over the last few years. Folk - a musical tradition with roots in the pre-electric world - is now becoming the new 21st-century pop phenomenon.
Get Folked: The Great Folk Revival explores the current resurgence in its popularity.
Is it the antidote to manufactured music, the new punk, or simply evidence of the enduring appeal of this age-old musical form?
This programme features first-hand testimony and intimate, specially shot musical performances from a cross-generational cast of legends, new and old.
Richard Thompson, The Lumineers, Jake Bugg, Frank Turner, Akala, Donovan, Martin Carthy, The Unthanks, Alt-J, Newton Faulkner, Seth Lakeman, Bob Geldof and Ade Edmondson are among the contributors.
