Mercury music prize nominee Sam Lee is a folk singer, a countryman and an impresario. Through his Nest Collective he promotes scores of different folk gigs and events every year. In this episode of Folk on Foot he invites Matthew to join him in a Sussex wood in the middle of the night as he leads a group of people on a silent walk to hear him sing with a nightingale. The bird appears un-phased by the arrival of the group and seems to respond as Sam starts an improvised duet. The next day Sam and Matthew retrace their steps in daylight, reflecting on the power of this mystical experience.
