The Black Heart Procession @ The Arches, 15 May

Ryan Bisland was a strange choice to open tonight's show. Undeniably a gifted acoustic performer, his upbeat, polished style seems at odds with the gloriously sombre self-indulgence of our headliners. Certainly his questionable decision to cover THAT Gina G song does nothing to redress the imbalance.

Bisland is rapidly followed by former Y'all Is Fantasy Island front-man and soloist Adam Stafford – by contrast fitting perfectly on the bill. Undeterred by some minor technical hitches, his set – a complex musical maze of vocal and instrumental loops set to some distinctly David Byrne-esque choreography – is truly inspired, boding well for his LP in August.

Dead Man's Waltz – the darker alter-ego of established Scots group Injuns – race on stage swiftly after. Again, they complement the main event beautifully, incorporating accordion and some well-judged humour into a solid handful of songs. Their set is only slightly marred by the overwhelming volume of the bass, but the band remains focused and finishes strongly.

The Black Heart Procession is stripped right back to founder members Pall Jenkins and Tobias Nathaniel tonight, limiting their repertoire as a result. Yet, utilising only a piano, one guitar and a saw, they manage to beautifully synopsise much of their career into little over 40 intensely gloomy and wonderful minutes. A Cry For Love and The Letter are especially devastating in their simplicity. For much of the show Jenkins stands – dressed entirely in black and wearing shades – with the microphone by his side, singing into the ether and making the most of the Arches' glorious natural acoustics. By the time his voice starts to finally give way and they finish an encore, there's barely a dry eye in the house.
