Despite being perhaps slightly miffed by the arrangement of Cab Vol's Monday Night "disco" that has forced their performance to be pushed back to an unsatisfactorily early hour, tonight Metronomy are quick to warm to an enthusiastic Edinburgh crowd.

The Metronomy of 2011 are a much more formidable proposition than when Mount created their first record, Pip Paine (Pay the £5000 You Owe), in 2006. In recent times the band has been boosted by increased strength in numbers, with Anna Prior and Gbenga Adelekan on drums and bass joining Mount and Oscar Cash on keyboards to create a collective full of an infectious energy.

The music has come on considerably as well, with latest full length effort The English Riviera receiving widespread critical praise and displaying far more sophistication than previous new rave effort Nights Out. Current 6music playlist favourite The Look and We Broke Free, included in tonight's hour long set, are ideal demonstrations of this new creative drive.

Their show tonight is weighted towards older content, with many of the songs from Nights Out forming the backbone of the show. Their live performance could perhaps do with more of the guile and style of their latest recorded effort, but that does not seem to matter too much of the crowd tonight, with an hour of shameless indie pop hits like Heartbreaker, A Thing For Me and Radio Ladio proving the perfect exam distraction for the student-dominated audience.

Even though we are told that the time constraints imposed by the imminent Trade Union night rule out the possibility of an encore, the feverish crowd are unwilling to let the band's rare Edinburgh excursion end too prematurely, and the four-piece are persuaded to return for an impromptu rendition of jumpy instrumental On The Motorway.

This is clearly a band that revels in a live setting, and although their show could be perhaps do with a further injection of sophistication, occasionally there is nothing wrong with the odd celebratory indie sing along. Uncomplicated in their lyrics and playful in their performance, Metronomy are surely the perfect band for a sunny Saturday at a festival.
