It has been an interesting year for singer-songwriter Lewis Capaldi - the kind that upcoming artists can only dream of.

Having yet to release his debut album, Capaldi has managed to sell out a UK-wide tour, work with the hottest producers and take home 'Breakthrough Artist of the Year' at the Scottish Music Awards.

The likes of BBC Sound Of, Evening Standard, Independent and Sunday Times Culture have all tipped him as the next big thing.

His most recent London show at the Scala even saw distantly related fan Peter Capaldi (12th Dr Who), turn up to show his support.

But the Glasgow-born performer classes his slot on the King Tut's stage at last year's TRNSMT Festival as the turning point in his career.

“I had a show in Berlin the previous night and we had to fly over so I wasn't sure what to expect", he explains.

“It was the day my second single came out and people were there in their droves, so that was a bit like 'wow people are actually coming to listen to this'.

“Ever since then, basically every show we’ve done has sold out.”

One of the sold out shows included his headline performance at Glasgow O2 ABC, which was queued down Sauchiehall Street before doors opened.

Hundreds of fans turned out to watch Capaldi off the back of just four songs.

“The fact that my show sold out off my EP songs is amazing, I’m absolutely gassed.

“I put it all down to my managers and team - if there's no people there to get the music places where so many people can hear it, there’s no point.

“I’ve been gigging around Glasgow since I was 12, playing to nobody.

“I was playing to nobody two years ago. It’s mental to see the change and get it to the point where I can play to people.

“I think when we released Bruises last year it just went off. That song was never meant to be the song that it is, it wasn’t meant to be heard by so many people. It was supposed to be an introduction so you could kinda get what music is about.

“On this tour I've been surprised that people know every song on the EP. If I knew four songs for one person I wouldn't necessary pay for a ticket to see them."

The song has become so popular, it’s been remixed and played at clubs around the country.

Capaldi is one of several Scottish acts tapping into an unprecedented level of success with very minimal mainstream airplay.

The announcement of his latest show - a headline slot at Glasgow Barrowlands - is proof of the power of social media and Scottish fans.

He will be following in the footsteps of the likes of Gerry Cinnamon, who also played sold out the ABC and attracted a massive audience at TRNSMT, off only a few songs.

Both Cinnamon and Capaldi will be taking the leap from King Tut's stage to Main Stage this year.

“There’s a few of us who have gone from both stages, it's unbelievable.

"It’s the first time I’ve been on the main stage at a major festival so to do it at a home show is incredible.

“It's great credit to TRNSMT and DF for giving us the chance and it's good for other performers to see that the opportunity is there if you grab it.

“To have a place where all these people come to see me, its wild. TRNSMT was one of the moments that I was kind of shocked - then Dublin, Manchester, Nottingham and London were sold out.

“Gerry is a perfect example. Scottish people with Scottish artists, they'll always back you if you seem alright. It’s pretty wild -it's definitely a Scottish thing.

“If you make that much noise in Scotland, people elsewhere are going to hear. Especially in London.”

The main selling point of Capaldi's music is his effortless vocals and self-proclaimed sad songs that tap into even the most repressed heartbreak that you've experienced.

Audiences at his show range in age and gender with heartbreak and a love of good ballad uniting them all.

Capaldi adds: “I definitely think there are people who have latched onto it.

“It’s amazing to see people screaming back lyrics about my ex-girlfriend from when I was 18.

“For some reason people have just taken into their arms and enjoyed it. And if I can give people a bit of respite which is great.

“I take influences from loads of people, it’s more like I see Kendrick and Kanye doing amazing things and I want to harness that.

“Some of my other songs are a lot faster but aren’t depressing. There's definitely sounds that people haven't heard.”

Lewis Capaldi will play TRNSMT Festival on Sunday July 8.

Tickets for his show at Glasgow Barrowlands go on sale Friday at 9am.
