How much difference can a killer festival season make to an artist's profile? We asked Spotify to help us find out: we gave them a list of 12 of the year's biggest break-out stars, and in return, they told us who had experienced the biggest increase in Spotify streams from May's Great Escape to September's Bestival. In 12th, it's Australian slacker Courtney Barnett.
Number 11, meanwhile, is London electronic production duo Gorgon City, who benefitted from slots at big-hitters like Glastonbury and Bestival.
Wolf Alice have been favourites in the NME office for some time, now – and even though they don't have a full album to be streamed on Spotify yet, their busy summer schedule including Glasto and Reading And Leeds paid dividends.
Cambridge electro-troupe Clean Bandit are ninth – and, like Wolf Alice, they saw their popularity on Spotify explode during the height of festival season.
At eight is Leeds post-punk Eagulls, who released their self-titled debut LP earlier this year. Longtime favourites of NME's Radar section, they clearly impressed a lot of festival punters, too.
Blackpool lot Darlia – the snottiest grunge-loving kids around right now – are at number seven. They performed at The Great Escape, Darlia and Glastonbury this year.
No-one does debauchery like sixth place on our list: London's infamously nasty and horrible Fat White Family. They came to Glastonbury, they saw Reading And Leeds and they conquered The Great Escape.
It's clear that festival season can be a massive boon to your popularity – but some artists have taken that upswing and turned it into even greater momentum. Charli XCX, for example, saw her average streams on Spotify increase by 31.67 per cent by the end of the summer.
Circa Waves – long tipped for greatness by NME – got a massive boost from their hard summer of slogging, too. Their turn at this year's Reading And Leeds was one of the season's finest, and it seemed to make a lasting impression on you lot: by the end of September, their Spotify streams had increased by 55.60 per cent.
Blimey. Playing Glastonbury, Reading And Leeds and loads, loads more certainly did wonders for Jungle this summer, didn't it? By the end of festival season, their streams had increased by 246.08 per cent.
Little surprise here: Summer 2014 was the time for Royal Blood to become absolutely massive, with Number One albums and sold-out tours. Tents were packed for their Reading And Leeds show, and it seems lots of those people were eager to hear more once they got home: Spotify say had a 617.72 per cent increase.
But the King of the festival-aided streaming boost is... George Ezra! The stats are mindblowing: from May to September, his number of streams per day had increased by 843 per cent. Not bad for someone who only released their debut album in June, eh?
