Recent politics surround the EU and nationhood, fantasies of Irish Sea bridges and trading borders more porous than limestone have revived the granular rub between Eire and Britain, and the Celtic Tiger cool of the Nineties is a history module these days.

Sam Lee has a strong, richly resonant and recognisable voice – and equally strong beliefs. His album Old Wow has really caught the spirit of moment: it is already being hailed as folk album of the year, even the decade, and last night’s gig at EartH in Hackney, the London leg of the album launch tour, was packed.

The Dingle Peninsula is a thumb of land that protrudes into the Atlantic as if trying to hitch a ride from Ireland to America. The choreographer Michael Keegan-Dolan recently moved there, and its crags and vales and unspoilt coast have sucked him into an older, slower way of life that – paradoxically, because his work was and remains radical – has given him a shot in the arm.

In its seventeenth incarnation, Transatlantic Sessions - a concert comprising music from some of the finest names in Scottish, Irish and American folk - had its penultimate night of its UK tour in a packed-out Symphony Hall, Birmingham on Friday evening. At first it might feel like an overly large venue for a group of around fifteen musicians.

U-Bahn’s second-ever live show outside their home country Australia took place in Aalborg, in Jutland, in the north of Denmark. They were in this congenial, routinely rain-sodden city last weekend for Northern Winter Beat, the annual festival of established, offbeat and up-and-coming musical adventurers.

While there’s usually something for everybody on the Celtic Connections festival programme, where Glasgow’s midwinter festival tends to shine is in its collaborations and special events.

The Dartmoor folk star’s latest album launches into a dramatic retelling of the voyage of the Mayflower, from its departure from the iconic Mayflower Steps in Plymouth (actually, the real steps are down to the women’s loo at the Admiral MacBride pub) to their landing on what the locals on the other side of the ocean called Patuxet.

Folk music has always thrived in times of adversity and danger and in times when (to coin a phrase) “nothing is real”. All the above apply now and folk music, its roots in the dirt of our septic isle, speaks to us eloquently as balm, warning, and call to action.

The first album from the Boston-bred songwriter Squirrel Flower opens and closes with autobiographical songs. “I-80” opens with the artist - real name Ella O’Connor Williams - giving up on lyrics, poetry and, later, giving up on love, its rootless melody channelling the road west to Iowa where Williams went to college before building to a relentless crescendo.

What a lovely surprise. A debut album with its own sensibility that’s come out of the blue. Aoife Nessa Frances is from Dublin and the terrific Land of No Junction – the title comes from a mistaken hearing of Llandudno Junction – signals the arrival of a major new talent.
