TWELFTH Day are not so much a duo, but a two person quartet.

Their two distinctly different voices, the fiddle, and the pedal harp, build layer upon layer of a complex and constantly evolving sound, rich with rhythm, harmony and texture.

In the wordless communication that passes between Orcadian fiddler Catriona Price and Peebles harpist Esther Swift as they perform, the strength of their decade-long musical partnership, friendship and shared humour is pretty evident. It's that depth of connection, and tangible desire to have fun, that gives them an extra edge.

Twelfth Day are happy to be hard to define. Classically trained, they bring outstanding technical ability as well as an adventurous mix of folk, jazz, pop and classical influences to their compositions and arrangements - blended with the folklore and inspirations of their respective Scottish Highland and Lowland upbringings.

In Twelfth Day’s latest album Cracks in the Room (2017), produced by legendary English folk musician Chris Wood and mixed in the United States by Oz Fritz (of Tom Waits fame), a new personal exposure, of fierceness and strength, is evident.

The title track is about a woman trying to mould and cram herself into what’s expected of her; its rising hysteria brimming with the pair’s quietly wild humour. The strong words of their Syrian friend Maya Youssef on her country’s suffering brought the inspiration and title of Another Phase In History. There's also a nod to Nina Simone, one of the duo’s ultimate inspirational artists, in Great Green.

Twelfth Day play Whitehaven's Rosehill Theatre on April 27. Go see - they might just blow you away with their bold and inventive music.
