In 1969, a tranche of American musicians looked back to the country’s past for inspiration. Bob Dylan followed John Wesley Harding with Nashville Skyline. The Band’s eponymous second album hit the shops. The Flying Burrito Brothers debuted with The Gilded Palace of Sin. The rootsy was a default. But choosing to draw on country and Appalachian traditions did not have to mean playing it straight. On the amazing Farewell Aldebaren, Judy Henske and Jerry Yester used banjo and hammered dulcimer.

Water has featured prominently in Lisa Hannigan’s work since striking out solo on 2008’s Mercury-nominated Sea Sew: water that caresses and relaxes; water that turns deadly and drowns. The water in At Swim is the water that the singer finds herself adrift in; the water that she had to cross between her home in Dublin and a new love in London as she pulled her third album together; and - yes, let’s go there - the water, murky and all-consuming, that typifies Aaron Dessner of The National’s production, and makes him Hannigan’s perfect foil.

Honestly, you wait years for a lengthy project to come to fruition, then two turn up at once. However, while The Avalanches had to contend with people tapping their watches and sighing wearily, The Earlies’ John Mark Lapham had only his own clock to watch. The measured pace and unhurried approach are reflected in the languorous song spectres he presents here.

Familiar words pepper the lead item on the 9am radio news: "Brexit", "Theresa May", "Boris Johnson". Yet the bulletin is delivered in the first language of the 49,000-population Faroe Islands. The self-governing region of Denmark may be a remote cluster of 18 North Atlantic islands, but the Britain-watching contagion has spread to a place which has never been a member of the EU. Denmark is. The Faroes aren't.

Becca Stevens’ limpid, luscious and artful fusion of Appalachian folk, jazz and indie rock found a perfectly empathetic setting in the Sam Wanamaker Playhouse, in an inspired choice for Lauren Laverne’s Wonder Women series of summer gigs. Stevens’ band began honing their connoisseur's stylistic melting pot more than a decade ago, and has been a fixture on the New York scene for some years. As she begins to make a name over here, British audiences are due for a treat.  

Devonian singer and accordionist Jim Causley released Cyprus Well, settings of his relative Charles Causley's poems, in 2013. What may be his finest album to date, Forgotten Kingdom, came early this year, and now he has released a second album of poems, this time by the great 20th century Cornish poet Jack Clemo.

The names may be unfamiliar, but Folque and Undertakers Circus are as good as better-known bands. Despite being musical bedfellows neither Norwegian band is as esteemed as, say, Trader Horne and Trees or Colloseum and Lighthouse. Folque issued their eponymous debut album in 1974. Despite line-up changes, the band was active until 1984. Undertakers Circus issued two albums, the first of which was 1973’s Ragnarock. The original band ran out of steam around 1976. Original pressings of Folque fetch between £40 and £80.

"Sunshine came softly through my window today..." How fortuitous that veteran Scottish tunestrel Donovan should have picked London's glorious first day of summer to stage his "Beat Cafe" event at the Palladium. The plan was to rove across his back catalogue to celebrate his 70th birthday (which actually falls on Tuesday) as well as his half-century in the music business.

Set in the grounds and rooms of the Master Shipwright’s Palace on the Thames at Deptford, Unamplifire brought together more than 30 artists over eight hours, with new and ancient folk and world music stirring from the riverside wing of the building – a stripped-to-the-plaster-and-floorboards palace, one you might find yourself in after a revolution. Built by master shipwright Joseph Allin in 1708, it’s a rich historical anomaly bordering the bleak remains of what was once the King's Wharf, established by Henry VIII in 1513, and about to be redeveloped by a Hong Kong investment company.

Is there anything left to say about Sandy Denny? Sadly, she cannot say anything herself, as she died in 1978. So it’s left to what she released during her lifetime, posthumous appraisals and reappraisals, and packages and repackages to do the talking.
