GLASGOW is set for one almighty pop party.

The Radio 1 Big Weekend arrives this weekend, offering a huge range of acts, from pop superstars like Pharrell Williams to massive rock bands like Kasabian and some top local talent, too.

Those lucky enough to have snapped up tickets should surely find plenty to their taste when they head to George Square for a dance-centric night on Friday, and then at Glasgow Green over Saturday and Sunday.

Here's seven questions ahead of the event.

1: How will Coldplay's new album come over live?

Ghost Stories hasn't just had a mixed reaction from music critics, it's also likely to split the group's fan base too.

Gone (mostly) are the big anthems of before, replaced by more stripped-back material that, understandably, plays like a break-up record.

That's maybe not a great fit for a band headlining a bash that's like Top of the Pops on steroids, so perhaps they'll downplay new ones in favour of familiar favourites like In My Place and Paradise.

2: How many costumes will Katy Perry get through?

Always a colourful character, Katy's making a swift return to Glasgow after she brought the roar to the SSE Hydro last weekend for two gigs.

Those shows featured all the hallmarks of a great big pop spectacle, from a hit-packed set to an elaborate stage design and continual costumes.

There were cats, Egyptian mummies, fireworks and a rotating birthday cake.

Given she's topping the bill on Sunday, it seems likely some of her spectacular show will carry over, and perhaps there'll be a surprise or two as well.

3: What sort of reaction will One Direction get?

They're the biggest band in pop music, and arguably one of the biggest things going in pop culture as a whole.

Having said that, there's a love them or loathe them aspect to One Direction too, and plenty of people can't stand Harry Styles and company with equal fervour to those who love them to bits.

Getting them to appear at the Big Weekend on Saturday is a huge coup for organisers, especially ahead of their Murrayfield gig on June 3, and you'll be able to hear the reaction when they appear from across the city.

4: How good are Twin Atlantic's new songs?

Fresh off a recent jaunt with Thirty Seconds To Mars, Twin Atlantic are just getting bigger and bigger.

Their lengthy slog to success certainly has parallels with the path followed by Biffy Clyro, and the Glasgow noise-makers recently confirmed that third album Great Divide will come out in August.

The first new tune, Heart and Soul, apes Whitesnake's Here I Go Again and sounds gigantic, but whether they'll road test any more this weekend remains to be seen.

5: Can London Grammar thrive in a tricky atmosphere?

London Grammar's debut album If You Wait featured selection of gorgeous yet restrained tunes and the husky, stunning vocal of singer Hannah Reid.

Their live gigs, including a recent O2 ABC appearance, thrived on creating a similar sort of atmosphere as on record. That will be a lot harder to do in a big setting though, so will they manage it?

6: What up and coming acts can stand out?

Although the two main stages are dominated by big names, the BBC Introducing stage offers fresh talent a chance to make an impression.

Look out for some terrific Scottish talent in the shape of noisy duo Honeyblood, soaring indie popsters Model Airplanes and black-hearted rockers Baby Strange.

7: Who will Lily Allen fall out with?

Place your bets now for who Lily, who's appearing on Saturday, will exchange words with over the weekend. It's inevitable.
