The first thing that strikes you at 3am is the light, that strange disembodied glow of Norway’s midsummer midnight sun casting its rays over a landscape soaked in fantasy proportions –  sheer glacial drops of greenstone, sweet-water fjords cutting deep into the land, the forests of spruce and pine desending from steep mountainous peaks to the meadow grasses of the valley below.

On paper, Richard Thompson's career seems every bit as exotic as one of his songs: At the age of 18 he helped found folk-rock pioneers, Fairport Convention. Later, in the Seventies, he and wife Linda recorded several successful records together before retreating to a Sufi Muslim commune.

The first thing that hits you is the voice. Simultaneously full and fragile; assured, but with a distinctive, backnote graze that runs along it like barbs on a feather shaft, it sounds, at times, as if it’s ghosting itself. As well as lending textural gravitas to pretty much anything Meg Baird chooses to sing, it’s the perfect instrument for this collection of self-penned songs that appear, on first listen, to be haunted by the past.

The songs of Richard Thompson have always been tinged with a hint of bitterness and anger, passions that are tempered by guitar paying of near-miraculous fluency. His new album, produced with brilliance and tact by Wilco’s Jeff Tweedy, is no exception. The standards are as high as ever, and the self-penned material, with the exception of “Guitar Heroes”, a somewhat tedious homage to masters of the instrument, is characterized by Thompson’s usual mix of poetry and irony.

For many, Mark Knopfler will forever evoke a golden age of Eighties' soft rock. His headband might have been easy to mock but his blistering, finger-picking was undeniably thrilling. Latterly, though, Knopfler has travelled a less commercial path. Still, while his folk tendencies may not be everybody’s cup of tea, there's certainly more to Knopfler than just melancholy ballads. For much of last night he treated the O2 to tantalising glimpses of his former, more rocking, self.

It takes a particular combination of talent, guts, perseverance and sheer bloody-mindedness for an artist to take the creative decisions that Thea Gilmore has across her approaching 20-year career and get away with it – thankfully, all qualities that the Oxford-born songwriter has in spades.

Almost two decades into a distinguished career, nobody would have judged Thea Gilmore for indulging herself with a greatest hits collection – indeed, it’s something that record labels have been bugging her about for years.

Olivia Chaney’s reputation as a singular folk singer and songwriter has been bubbling on and off the radar for some years now. There were EPs in 2010 and 2013, and she featured on the excellent Peter Bellamy tribute, 2011’s Oak Ash and Thorn, and she has toured solo, as well as worked with Alasdair Roberts.
