Glasgow singer Roddy Hart doesn’t mind that there’s people who know his voice but not his music.

The troubadour presents a weekly show on BBC Scotland, delving into new Americana and folk rock.

He’s also known as the man at the helm of the popular Roaming Roots Revue shows at Celtic Connections, which are set for their fifth year.

However he’s also got his own musical career, with his second album with band the Lonesome Fire released last year.

“I don’t worry that there might be people who listen to the show but not our music,” says the singer, who plays St Luke’s on Saturday.

“I would never play my own music on the show, because I know how difficult it is to be heard, and there’s certain lines that I wouldn’t cross with the different jobs. I always feel like I’ll deal with each project as it presents itself.

“I’ve always been interested in music and had a passion for it, and I’ve always written songs – that’s something that’ll never go away, whether it’s for lots of people or just myself.”

Roddy started out writing songs as a purely solo act, but after two albums and an EP on his own he recruited the Lonesome Fire to give a fuller backing sound. His second record with the band, Swithering, represents the full band more than before, with the rest of the group chipping in with ideas, rather than all the creativity coming from just Roddy.

“With the first album we were finding our feet as players and how we related to each other,” he says.

“We were close as friends but it’s very different trying to work together musically. I was coming in with songs and we only had a finite amount of time to make it as we were working with a producer from London, so there were practical reasons to me writing everything too.

“This time around we’d been on the road a lot and had a lot of shared experiences, and I think the older I get I’m not as inward looking with my writing. I still want it to come from me because it’s my voice, but I wanted to open the doors and test myself and the boys in the band.”

That may have resulted in a fuller, more varied record than before, but it also left the singer doubting himself as they made the album, as he adapted to other voices having a say.

“There was a lot of self doubt as to whether what we were doing was right and whether adding in too many people would water down the vision of what we were wanting to do,” he admits.

“But I look at the album now and it’s very varied – you can certainly chose bands and moments that influenced things, but as an overall piece it’s quite eclectic from song to song and that’s because everyone had an opinion and was throwing ideas in.

“That’s what makes it interesting, and why we called it Swithering – there was a lot of uncertainty, and that uncertainty ended up becoming a strength.”

Something that is absolutely certain is that the Roaming Roots Revue on Saturday January 28 will be one of the biggest highlights of Celtic Connections. Guests this year include Sarah Jarosz, Jesica Hoop, Frightened Rabbit frontman Scott Hutchison and former Delgados songstress Emma Pollock.

This year the event is inspired by one of the main themes of the whole festival, which is celebrating female singers, with some surprising choices being represented.

“We found that a lot of the artists we got were alternative, so although there’s your big female acts like Joni Mitchell being covered, there’s also Bjork and the Yeah Yeah Yeahs.

“That helps keep it different as we wanted a real variety, although we’d maybe draw the line at Britney Spears and music that’s as poppy as that!”
