To win the Best Duo category at the 2015 BBC Folk Awards is quite an achievement at any stage of an artists’ career. But just two years prior to this accolade Josienne Clarke and Ben Walker were virtually unknown on the folk scene, so their success is quite remarkable. While much of their music is characterised by lush chamber ensemble orchestrations, what truly sets them apart is the combination of Josienne’s exquisitely nuanced, emotionally affecting voice and Ben’s intricately expressive, adroit guitar technique. They cite Sandy Denny, June Tabor, Nic Jones and Pierre Bensusan as respective influences but theirs is a captivating sound that’s all their own. This duo inhabit songs that are centuries old, making them personal and present again, and their gift for pricking the heart with tales of everyday love and loss makes their music a rare and precious thing. Josienne and Ben will perform on Sunday in the afternoon concert in Marquee 1 and the evening concert in Marquee 2.
