The titular “lighthouse of glass” is a place where the narrator is “crying into the sun,” in which there is a need to “stand by my solitude.” Choosing isolation and self-determination are themes running throughout Lighthouse of Glass the album and how Sweden’s Sofia Härdig has approached recording these 10 songs. As well as the songwriter, she is the arranger, engineer, producer and main instrumentalist.

Stereo Instrumental Music was recorded in July 1976 and originally issued only on cassette. The release was organised by what was credited as the “Sun Shine Music Shop,” an enterprise which seems to have left no additional imprint. No further “Sun Shine Music Shop” albums are known.

A pizzicato violin opens Song Over Støv. Gradually, other instruments arrive: bowed violin, a fluttering flute, pattering percussion, an ominous double bass. They merge. The climax is furious, intensely rhythmic. Suddenly, it is over.

The sticker on the front cover says “The heaviest proto-metal compilation ever released.” And considering the label behind Yeah Man, It's Bloody Heavy is Rise Above, founded by former Napalm Death and Cathedral frontman Lee Dorrian, this is not idle hubris.

It took until the last song before Lauren Mayberry started to well up onstage, which was good going. The singer had mentioned early on the prospect of a hometown Glasgow gig for her solo career had left her emotional all day, both with joy and fear.

On the cover of her eponymous debut album, the Bolton-raised Toria Wooff reclines on a church pew located in Stanley Palace, a 16th-century mansion in her adopted city of Chester. In her hand, a Celtic Cross. Such imagery implies that what will be heard on the grooves within the sleeve might cleave to forms of gothic-inclined British folk. This, though, is not the case.

The thrill of hearing “Crawdaddy Simone” never wears off. As the September 1965 B-side of the third single by North London R&B band The Syndicats, it attracted next-to no attention when it came out. The top side of the flop 45 was “On the Horizon,” a version of a Ben E. King B-side. After this, The Syndicats’ time seemed to have passed.

The body language fascinates. Mercury Rev’s frontman Jonathan Donahue could be playing a theramin. The arm movements fit the bill, yet the putative instrument is absent. At other points, his arms are outstretched, palms down. He might be projecting invisible rays in the manner of a silent-screen magician or, when he's in front of the band’s guitarist Grasshopper, absorbing invisible energies.

Lizz Wright’s exquisite singing breaks all boundaries between soul, gospel and jazz. In so doing she channels many interwoven strands of the African-American experience. Wright thrives on singing to an audience: her recorded output is wonderful enough, but, a child of the church, the sacred ceremony of raising the spirit in myriad ways is undeniably her home ground.

Wardruna are something of a modern musical phenomenon. Part Scandinavian folk revival, part prog rock epic and part pagan ritual, their wide-screen performances are a beautiful and mesmerising celebration of repurposed ancient traditions, the natural world and the power of singing together.
