TONIGHT Twin Atlantic will play the first of two nights at a sold-out Barrowland - but they're already eyeing up bigger venues.

The Glasgow foursome are enjoying a terrific 2014, with second album Great Divide pushing them into music's major leagues.

Now the quartet - singer Sam McTrusty, guitarist Barry McKenna, bassist Ross McNae and drummer Craig Kneale - are eyeing up a huge gig next year.

"In Scotland we want to take the move up to playing an arena," says Craig. "We've talked about it, and would love to finish off the album campaign at the SECC or the Hydro next year, just for the challenge of seeing if we could do it.

"We feel that we know what we're doing and can get a room on our side, so that's definitely a goal. We want to keep challenging ourselves - you don't want to get stale by doing the same things, so you want to push it."

That doesn't mean they're not relishing the opportunity to play at the Barrowland tonight and tomorrow, with tickets like gold dust for the lads' first Glasgow shows since Great Divide's release.

While it's not the band's first Barrowland experience, Craig reckons there will always be nerves at playing a venue steeped in Glasgow's gigging culture.

"We're always going to be nervous playing the Barras, but in a good way," he says.

"It's just because you don't want to let people down. When I've been to gigs there that there's an extra excitement about shows there. It's a big room, but it always feels like everyone is crammed in, and it just sounds great. It's one of those venues that you couldn't recreate in another room because it just has a magic to it."

It's also a building that the Twin boys have visited many times over the years as punters, going back to the days when headlining there was nothing more than a faraway dream.

"When I was younger one of the very first gigs I went to was seeing the Mars Volta there," recalls the drummer.

"As a musician it was amazing, I was just 15 or 16 and it was one of those gigs that I've never forgotten. I don't think I've ever been to a bad gig at the Barras - bands always seem to raise their game there."

Twin themselves have been steadily raising their game over the past several years. Much like Biffy Clyro, a band they're regularly compared to, the group started off playing the city's tiniest venues, and worked their way up the ladder.

If their first full-length album, Free, put the group on the map, then Great Divide has set the band off on conquering the world, with the likes of Heart & Soul and Brothers & Sisters enormous pop-rock anthems.

It's undoubtedly the band's most poppy work, which some long-term fans have been disappointed by.

"We weren't dumb to it, we knew writing the album that it was poppier than before," says Craig. "It's partly the age we are, we're in our late twenties now and our tastes have changed a bit, we're not just listening to Rage Against The Machine any more. We knew Heart & Soul was poppier than anything else we'd done before, but we loved the song.

"It was a bit scary - there's probably a few fans we lost with that song but we made a lot more in terms of who hadn't heard us before and then got into our earlier work because of it."

The record's souped-up feel also let the cheerful sticksman cut loose on the drums more than before.

"For me personally, the new ones are a little more complex for the drums so it's been good to push myself," he says.

"On something like I Am An Animal we wanted it to have a big glam rock feel, and that let me go crazy on the drums because the guitars are quite regimented on it."

The band have also been forced to spend time away from Glasgow recently, but Craig admits it's been good to get back home.

"We've been in London a lot over the summer and I just don't feel very relaxed there, whereas you come back to Glasgow and there's a calmness there," he adds.

"No-one gets too big for their boots here. Everyone stays grounded and I love that about the city. I don't think we'll ever lose that."
