IT was only a few years that Glasgow pop-punk band Altered Sky were watching their favourite acts on Kerrang TV.

Now they’re the ones being watched, as they get ready up to release their debut album later this year.

The foursome, who are based in Dennistoun, already have a dedicated teenage following.

“It’s always something we always dreamed of having, but it’s quite surreal,” says bassist Ross Archibald, ahead of the band headlining G2 at the Garage on Saturday night.

“I remember when I was 15, watching Kerrang and loving the bands on it, so to think that one day I’d have a band on there was incredibly weird.

"What happened last year (when they got TV and radio airplay) was insane, and seeing all those 15 and 16-year-olds cheering us on now, I can put myself in their shoes.

“It’s still surreal to us to have these fans so passionate about our music, and there’s no better feeling than playing live and engaging with them.”

The quartet also feature singer Ana Nowosielska, guitarist Richard Passe and drummer Amy Blair, and their upbeat, catchy sound is perfectly suited for the charts.

Recent single Bury It All has offered a taste of what’s come in the future, with an album due to land by October or November.

They’ve long been one of Scotland’s hardest working groups, but although they’ve got a female singer in Ana, Ross doesn’t feel they’re the same as many bands they get compared to.

“Having a female singer means people assume we’re another Paramore or another Tonight Alive or just that we’re copying whatever female fronted acts are doing the rounds at the moment,” he says.

“We get that every time when we release something, there’s people saying ‘oh Ana’s hair is like Hayley Williams’, and things like that, you can’t escape it.”

The band’s material thus far including last year’s Stop and Live EP, has tended towards angst-ridden pop-punk, with big choruses aplenty.

For their upcoming debut album the band wanted to mix things up a bit, as they worked away in Wales for two weeks with producer Romesh Dodangoda, who’s worked with Motorhead, Funeral For A Friend and Bring Me The Horizon, among others.

“On the EPs we’ve released we’ve not had as much chance to be varied, but with an album you’ve got more tracks, and more chances to be creative and experimental,” he says.

“We didn’t go too far out there, all the tracks are still within that radio friendly and commercial genre but there are different things on it.

"We’ve done our first full piano one, just piano and vocals, and it’s a slow ballad.

“A good thing about Romesh is that he gets that atmosphere, that dynamic, and getting that light and shade in there, so hopefully that will come across in the finished product.”

Getting to the album wasn’t always an easy process.

Ross believes it was last year’s Stop and Live EP that really pushed them in the right direction, coming at a time when the band weren’t certain of the next step.

“After our first EP we lost a bit of momentum, for various reasons, and we thought we weren’t ready to try and make an album,” he recalls.

“So we did another EP to see how it went.

"After the release of it we managed to keep the momentum up and that did lead to us going into doing the album. It was an important stepping stone.”

Now the group seem to have their confidence up. The band’s own information talks up their ‘uncynical self-belief’, but Ross claims that doesn’t mean the band are all getting big heads and dreaming of stadium gigs just yet.

Instead it’s looking to the next step, in this case tomorrow’s G2 show.

“I suppose it’s just confidence without being cocky or going overboard with it,” he says.

“We have a one track mind as such and there’s a belief in ourselves.

"We’re ambitious, but not too ambitious - it’s having a focus on what we’re doing that’s important.

"You can let your imagination run wild and it’s great to have goals, but it’s having that focus on what we need to do to make the next thing that’s really important.

“That stops us getting carried away with ourselves and thinking we’re going to be huge.

"It’s about making the next step happen.”
