IT sounds like a trick question – would you rather record an album in Battersea or Los Angeles?

But for indie pop chart-toppers Bastille there was only one answer, as they shunned going Stateside to make second album Wild World at home.

“People at our label asked us if we wanted to work with a big producer, or go to Los Angeles,” explains the band’s keyboardist Kyle Simmons.

“We were like ‘that’s not how we work’. Mark Crew (who produced the record, along with the band’s singer Dan Smith) is incredible, and we love and trust him because we know he gets the best out of us.

“He’s basically the fifth member of Bastille, and we got him out on tour with us – we got a little room backstage set up at some shows and worked on stuff there. We didn’t want to take months out to record the album, we just did it when we were touring, and then at the end we came together to record it with all the instruments in the studio (in Battersea).”

That approach seems to sum up Bastille, a band unaffected by fame. Debut album Bad Blood may have delivered several hits, including the massive Pompeii, but the London foursome still appear surprised by just how big the band have become.

Further proof of their success comes with the fact their next tour is arounds, including a show at the SSE Hydro on Saturday.

“Playing down things is the Bastille way,” admits Kyle.

“It isn’t that we don’t believe in what we’re doing, but we know a lot of amazing bands that we thought would be massive, and then they get dropped by their labels before even releasing an album.

“If it isn’t working out for them then it makes you think more realistically, like ‘wow, this is a nightmare industry’.

“Playing arenas is something we never thought we’d do, not through lack of faith in the music but we were just trying to be realistic.”

Saturday’s Scottish show comes after a summer appearance at T In The Park, and the band have been regular visitors in Scotland since they first formed. The fact that they started out playing the likes of King Tut’s means that Kyle still can’t get his head around the Hydro as their next stop.

“It’s going to be amazing,” adds Kyle.

“Glasgow is always fun and we always sneak out to a few bars afterwards and stuff, but it’s crazy to be doing this. I’ve been up to Glasgow before to see friends at uni there and I’ve played in King Tut’s, so to be coming back to play this size of show is incredible.

“Obviously Nice N Sleazy is where you go after a gig in Glasgow and we’ll probably try to get there or the Garage after the gig – we had a few nights there in the past.”

One of the advantages of being in a low-key band like Bastille is being able to enjoy the success of fame without too many disadvantages. The laid back group aren’t being besieged by paparazzi or anything like that, despite being chart regulars.

“We’re really lucky, because I can walk around at home and not be recognised,” says the keyboardist.

“The fame side of being in a band is something we’ve ignored because we’re just not interested in it at all. Dan gets it more than us, because it’s his face fronting the band, but even then it’s a lot less than you might think.

“Even when we do get recognised, everyone is always really nice and just wanting a quick chat.”

Saturday’s gig is in support of Wild World, which reached No 1 earlier this year. Kyle believes the added emphasis on guitars this time around helped freshen things up, changing it up from the songs that featured on 2013’s Bad Blood.

“It’s such a normal instrument but because we didn’t have any on the first album, it’s added a completely new element to the sound,” he says.

“I guess that our influences are more obvious on this one, whereas the first one was more subtle, maybe with a wee nod to hip-hop in how we’d mixed the drums on a certain track or something like that. Now it’s maybe more something like having a Jack White esque guitar riff running through a whole song. We’ve not been afraid to just go for it this time.”
