Having announced its return to business last week after the summer break with one young band on the up, Celtic Connections Danny award-winners Rura, Edinburgh Folk Club presented two more rising acts on Wednesday.

Corran Raa are a two-fiddles-and-rhythm quartet who have just released their first album and must have put themselves in the running for a headlining gig here with their nicely voiced fiddle arrangements, strong, confident melodies and deft piano and guitar support on a repertoire that suggested highland, north-east and Shetland origins.

They were certainly complementary openers for Devon’s Carrivick Sisters, twins Laura and Charlotte, whose songwriting often focuses on interesting historical events near to home but whose major influences are more reflective of where the Mayflower sailed to than its point of departure.

Although just 21, they already have five years performing and recording experience – their latest album, From the Fields, is their fourth – and although Laura’s fiddle playing took a few numbers to find its mettle, they play a number of instruments with the sort of skill that must have caught the judges’ ears when they appeared in the BBC Radio 2 Young Folk final last year.

Switching between fiddle, guitar and her particular strength, Dobro (Laura) and guitar, banjo and mandolin (Charlotte) gives them a variety of arrangement possibilities, which they use very well in bluegrass, swing and old-time settings.

Their singing, despite their having attractive-sounding voices, unfortunately doesn’t always measure up to this instrumental prowess at the moment – their lyrics can be quite hard to follow – but with a bit of work they could yet put Devon on the Americana map.
