While bands such as The Birthday Party, Siouxsie and the Banshees and, especially, Bauhaus had a hand in inventing goth music at the start of the Eighties, it was The Sisters of Mercy who defined it. Their combination of black clad cowboy shtick, mirror shades and dry ice worked a treat. In recent years, there have been rumours that the band’s live shows are less than impressive, mentions of a tendency to focus on unreleased material while dressed in leisurewear.

Emmanuel (Anthony Ofoegbu) runs Three Kings Barbers in London. His assistant, Samuel (Mohammed Mansaray), is the son of his erstwhile business partner, who is currently in jail. Emmanuel is boss, surrogate father and — occasionally — verbal punching bag: Sam is a whizz with the shears and just as cutting with his tongue. 

Was it imagination or did The Waterboys’ audience at London’s Roundhouse, invited to sing along to “The Nearest Thing to Hip”, really sing extra-loud and lustily on the line “in this shithole”?

It was in the early 2000s in a tiny, gritty bar that I first saw Rodrigo y Gabriela live. Camden was less pretty then – a look was close to a glare and there were more spikes and kohl – the nineties were that much closer. I was right at the front, pressed up against a rib-height stage, alarmingly close to the percussive thrum taking place inches above my head. The atmosphere was heady, their acoustic performance electric. Their hands moved like fire, catching the area’s thrash sensibility – I’d not heard anything like it.

There is increasing urgency, commitment and assuredness about the way Laura Mvula performs her music. The context for her performance here was Love Supreme's day at the Roundhouse. As the event's main headliner and the stand-out performer, she really delivered the goods on Saturday night.

“Don’t love me yet,” replies Patti Smith to the first of tonight’s many excitable shout-outs. “Who knows, after 20 minutes you might be gone!” An unlikely scenario, given that this show – part of the Roundhouse’s annual “In the Round” series, which also features Ronnie Spector and Shirley Collins – sold out in nanoseconds and is packed with rapt fans.

It’s about to begin. The final performance on the final night – and only UK date – of the European Apocalypse package tour featuring four extreme metal bands. The 1,700 capacity Roundhouse is sold out. Touts outside are scrabbling for tickets. A curtain covers the stagefront. A procession of images flicker across it; ancient art, demons, gods and hellish conflict. Then the screen goes black. In large white gothic letters, words in sequence: LONDON. PREPARE. TO. GET.

There are good musical reasons why it might never have occurred to you to wonder how Lady Gaga would sound if adapted by Duke Ellington; Radiohead by Sidney Bechet; or Bruce Springsteen by Frank Sinatra.

The power of music solves every problem, at least when as bewitchingly performed as it was here. With the great mezzo Christine Rice voiceless for at least a night, and rising star Caitlin Hulcup singing for her from the midst of the instruments in the pit right at the centre of the Roundhouse, how could faithful Penelope's final acceptance of her long-lost husband Ulysses (Roderick Williams) achieve transcendence?

The creative partnership between Ed Harcourt and Martha Wainwright is an intriguing one. He is an out and out showman, full of stage presence, bravado and tinged with thespiness. She is an introverted, quirky creative, flanked by the comfort of a full band. But there's no doubting that together they make beautiful music.
