Tom Moore and Archie Moss are set to play tracks from their new album Spectres at the concert, which starts at 7.30pm.
Archie, 27, from Glastonbury, said: "We recorded the album in February last year and released it a year ago.
"It comprises 11 instrumental tracks and features new hybrid folk music with lots of electronic manipulation and looping.
"It means that we have just got more layers and that we can play around with. It's a much fuller sound and gives us the opportunity for texturing."
Their second album is set to further unite the deep and resolute harmony of Moss’s accordion with the texture and flow of Moore’s viola; with droning, whirring, sparkling layers of electro-acoustic grit provoking a subtle complexity of palette.
The pair are helping to re-define how British instrumental folk music is made after having learned their craft as two-thirds of the ground-breaking trio Moore, Moss, Rutter with folk guitarist Jack Rutter, who has since gone solo.
After becoming winners at the BBC Radio 2 Folk Awards in 2011 they have been touring the world with the likes of False Lights, Cara Dillon, Jim Moray, Nick Hart, and many others.
Now they find themselves at an exciting new point in their lives and careers - releasing their second album as a duo, setting up a recording studio in Tom’s native Norfolk, and very ambitiously forming a new record label Slow Worm Records to release the music of other adventurous and forward-thinking artists.
The label and studio were both launched in September aiming to specialise in ‘Folk meets experimental’ - focusing heavily upon instrumental music, capturing improvised performances, and film syncing.
Their tour takes in Penzance, Bristol and Manchester Folk Festival. To book tickets call 01249 701628 or go to https://poundarts.org.uk/
