“This is the third time we’ve played here and we’ve finally made it to the third floor,” joked Errors frontman Steve Livingstone, referencing Clwb’s triple-layered architecture. “There’s nowhere left to go now, except the roof!”

The Scottish threesome are certainly keen on Wales, later calling Cardiff their spiritual home and, in the process, displaying an affinity with an audience who remained utterly engaged throughout the evening’s performance.

Opening proceedings was Tom Rogerson, usually keyboardist with math-rock trio Three Trapped Tigers, but who, tonight, was performing in his own capacity as an improvisational synth maestro, his rig on the floor rather than the stage. As would be expected, this bordered on self-indulgent at several points during the half-hour set, but his buzzes and tinklings remained transfixing during their mellower moments.

Next came Remember Remember, a Glaswegian six-piece who brought with them an entire GCSE music class worth of instruments, ranging from glockenspiels to recorders and some kind of ball and stick thing. Surprisingly, their set wasn’t as twee as this instrumentation made out, occasionally giving off a distinctly medieval vibe in amongst Sigur Rós-esque minimalism.

When Errors eventually took to the stage, the room became appropriately crowded. While they may be three young fellows from Glasgow, who perform some kind of bastardised electronirock, they can certainly make the ladies in the front get down. Indeed, no sooner had opener ‘Tusk’, the first track from latest album Have Some Faith in Magic, reared its muscular head than the booties started shaking and arms were a-flailing. This led to some frustrating moments where viewing angles were restricted to moments when the young women in front were swaying to the left, but, hey, it was all in good spirit.

The set certainly had a focus on the aforementioned new release, and with good reason: ‘Magic’ has already proven itself to be one of 2012’s musical highlights, with intricate layers of synths and guitars giving Errors a sense of genuine artistic progression. This progression came despite the departure of founding member Greg Paterson last October, and the band were thus faced with the formidable task of recreating both their previous live material and new compositions onstage. Playing as a three-piece therefore necessitated an over reliance on samples, with bass lines predominantly supplied by MacBooks, although a real bass guitar came out for rumble-heavy numbers like ‘Beards’ and ‘Earthscore.’

As well as displaying a dry wit, Livingstone also dabbled with a spot of singing. Of course, this was heavily effected with digital harmonies and echo, but in doing so supported the band’s belief that vocals are just another instrument in their arsenal. On the night, they seemed to add a euphoric sense of achievement whenever they cropped up, as if the band had introduced another member rather than being one man down.

If it was apparent from the off that Errors were popular in Cardiff, then the opening chimes of ‘Mr Milk’ (from the band’s first release, the How Clean is Your Acid House EP) were about to make sure they weren’t going to forget it. The dancing amongst the audience had got more intense and, some might say, violently so. This kinetic commotion continued right up until the evening’s close at the hand of ‘Holus-Bolus’, with requests for an encore going ignored. But Errors had already won everyone over that night: they were aiming for the roof.
