Emily Barker will also be showcasing her side project, Vena Portae in the Duck Shed venue at Purbeck Folk Festival.

Vena Portae is a three-piece Anglo-Swedish-Alt-Folk-Retro-Pop collaboration between Emily, storyteller/composer/performer Dom Coyote and actor/musician Ruben Engzell. They recorded their debut album in the depths of a Swedish winter and decided to wait until summer to release it, along with a single, Summer Kills, tellingly remixed by Peter Morén, of Peter Bjorn and John fame.

“The Sunday at Purbeck should be quite a day for fans of Emily’s band,” says festival director Paul Burke. “We loved an album released a few months ago by her multi-instrumental band member, Gill Sandell. After Emily’s late afternoon concert on the High Barn, Gill performs on the Fire Stage in the evening. It was icing on the cake when Emily’s manager contacted us to offer Vena Portae as well.

“Emily Barker is one of the most inspiring and perceptive songwriters we have come across. She played our very first Purbeck Folk Festival at Steeple Leaze in 2009. At the time she was unknown but, with her four-piece band, she performed an outstanding set and we’ve wanted to welcome her back ever since.”

Now in its sixth year, Purbeck Folk Festival’s inclusive booking policy ensures an eclectic mix of outstanding original new folk, as well as established roots, traditional and world music in a fun, family-friendly environment. This year the headline acts include Eddi Reader, Lloyd Cole, Sally Barker from The Voice, The South, Idlewild Acoustic, Turin Brakes, Nizlopi and Chris Wood. The four stages are contained in the farm’s covered barns with a marquee venue that hosts open mic sessions.
