It's four o'clock in the afternoon and Ryan Potter has barely slept.

The Hunna's frontman has been up all night recording guitar parts for the band's highly anticipated debut album and the exhaustion's starting to kick in.

"I'm so tired," he says. "I've had hardly any sleep, I was in the studio until 7.30 this morning."

It's hardly surprising that sleep seems to be eluding the four-piece given their meteoric rise to fame.

Almost completely unknown six months ago, the British group have now played shows across Europe, signed a deal with US record label 300 Entertainment and are preparing for their UK tour.

"It's been amazing," says Ryan. "We had been working behind the scenes, just getting songs ready and making sure we were ready for it. We were confident in the songs we had because we were confident we had worked hard and they were good but the reaction's been more than we thought it would be. We're just taking it day by day and enjoying it."

As if that wasn't enough, their debut album is due out in August with a deluxe version already in the works.

"It's coming together really nicely," says Ryan. "We're nearly half way through and to hear all the songs coming together and hear the near to finished product for some of them is incredible because you start to get a feel for how the album's going to sound all together.

"So far we're really happy and our producer Duncan Mills is an absolute legend so he's on the same wavelength as us."

The group have also worked with Tim Larcombe, a producer famed for his collaborations with Halsey and Lana Del Ray, on the album and Ryan says his influence has brought a more hip hop focus to the record.

"Tim is amazing," he says. "He loves his hip hop which is great for us. When we're working together there's never really any issues, we just go with it and whatever feels right. We're all in it together and we know what we want to achieve and get from a song. It's a really nice process."

The inclusion of a hip hop influence in an album from a group that, on first listen, screams indie pop rock may seem unusual but it's something that may have helped the band achieve what many UK artists covet, a U.S. record deal.

The four piece were signed to the 300 Entertainment, home to Young Thug, Coheed and Cambria and Fetty Wap, earlier this year and will visit America for the first time in June.

"It's crazy," says Ryan. "To get that, especially this early on, is amazing and we're so excited to get over there.

"I think we're the first band they have signed other than hip hop artists which is great because we've got such big hip hop influences so we're really stoked for that.

"We haven't been over to the U.S. yet but fans have been asking us to come there for a while so now we're finally going we're excited to meet them and hopefully we'll go down well.

"A few of the acts on the label have said they really dig us too so that's exciting. Any advice they want to give us would be great because it's something we've never tackled before so we're still getting used to it all day by day."

However, Ryan says that the band are acutely aware that they would not be where they are today without their fans.

"Without them we wouldn't be able to tour at all or even exist," he says. "They are pretty much everything.

"We've always felt strongly about what we do and how we make our music and what it is about and to finally have it out there and have that amount of people having this reaction to it is amazing.

"It's something we've always wanted and meeting all of the fans at gigs, you can just really feel a connection and what people say about our songs is what we've always wanted so it's the best thing really."

The band are now preparing to bring their UK tour to King Tut's on Thursday, May 26 and Ryan can't wait to get back out in front of a Glasgow crowd.

"It's going to be amazing," he says. "I literally can't wait for that.

"Every time we've played Glasgow it's been awesome and the fans are completely off the chain.

"We love coming back. It's the first show to be sold-out on the tour so we're really happy about that. It's going to be a bigger show than we've done before in Glasgow and it's going to be super energetic. It's just going to be a room full of people there to forget everything and have fun and all be together in unity."

The band, who formed two-and-a-half years ago, filmed one of their first videos, Bonfire, in the city and Ryan believes they have a lot to thank Glasgow for.

"I feel like Glasgow fans have just really gone with it and taken us for who we are and what we are and they have really pushed it," he says. "Glasgow's a great place."

The Hunna will play King Tut's on Thursday, May 26.
