IT must be every festival organiser's nightmare – 8pm on Saturday night and one of your biggest acts is ready to take to the main stage when the generator packs up.

An expectant audience starts to twitch, wondering why The Hidden Cameras' set hasn't started yet.

Then they're told the power's gone.

If this were Reading or Leeds, there would be a riot. But this is Derbyshire, this is Indietracks and there was no need to panic.

Instead the six-piece picked up their guitar, maracas and a flute for an impromptu four-song acoustic set, making them heroes of the weekend.

Within just half an hour, dismantled drums and unplugged guitars were shifted to one of the smaller stages, schedules tweaked and the 1,500 punters kept smiling.

Now in its fifth year, Indietracks has carved a niche in the festival market for lovers of twee, high treble, bar-chord guitar bands.

Groups from across the globe clamour to be invited and this year's multi-national line-up was no different.

Acts from Japan, Greece, Denmark, Sweden, Spain, USA, France and Canada rubbed shoulders with legends such as Norman Blake and Euros Childs, whose new band Jonny were the pick of the crop on Friday night.

Raising the roof inside the church stage on Saturday with their 60s-inspired pop fizz were Sockpuppets, from Copenhagen.

Singer/guitarist Louise Bang Olesen said playing Indietracks was a dream come true.

"We've been here as paying customers for four out of the five years and we only got the chance to play at this one because a band dropped out two weeks ago," she said.

"It was loud, hot and crowded, just how we like it."

Emma Hall is one of the organisers at the event, which has been taking place amid the backdrop of steam trains and locomotives at the Midland Railway Centre, in Ripley, since 2007.

This year she and her band, Pocketbooks, got to open when they played the main stage on Friday night.

Emma said: "This year has been amazing, what with the fantastic line-up of bands and the brilliant weather."

Hidden gems included two bands with terrible names, A History of Apple Pie and Milky Wimpshake, both of whom played inside a converted engine shed.

London-based electro due Victoria and Jacob brought some intelligent and fuzzy warmth to the church stage during Saturday's heatwave.

And it was humbling to watch Edwyn Collins, still recovering from two sudden brain haemorrhages six years ago, as he climbed up on stage and blasted out a stunning set of old favourites.

Indietracks is too polite to stick two fingers up at corporate festivals such as Reading, Leeds and V, but at the same time it doesn't need to. That's because it is so much more effortlessly cooler.
