As galling as it might feel to fans anxious not to miss a build-up, there remains something exciting about queuing for a gig.

As the soundmen sized up the acoustics and those already inside charged their glasses, the line to see Mystery Jets deepened outside the Corn Exchange. Excitement hung in the air, undiminished by flurries of drizzle on a chilly night.

Eventually, those unperturbed by bouncers warning of disappointment got in with some time to spare, their anticipation richly rewarded with a glowing display of hook-laden psych-pop from a group whose rapid maturity might well be about to see them evolve from cute and fuzzy indie to something far more substantial.

By their own faintly nervous admission, fourth album Radlands is a leap of faith – a concept record when it might have been easier for them to stick to sparkly singalongs.

But judging by tonight, their bravery only highlights their abilities, weaving from synth keys and twangy alt-folk to convoluted rock-outs, all without losing the momentum of a crowd with energy to burn.

In a particularly sweet moment midway through the set, Sophie-Rose Harper sauntered on stage to accompany the shimmering Take Me Where The Roses Grow.

Then the glacial dance-feel of Two Doors Down kicked in, embellishing the sense of romanticism without losing the booming drums that form the cacophonous core of their art.

Always reliable crowd-pleasers, their enhanced armoury gives them a new dimension. Their risk-taking has paid off.
