Bella Union champs, Ballet School (Rosie Blair, Michel Collet and Louis McGuire), are like a Delorean-delivered blast from the 1980s, drenched in a drizzle of Siouxie, Simple Minds and Cocteau Twins then dried through a contemporary pop mangle to create a crisp 2014 sound.

As their debut EP, Boys Again, showed, the Berlin-based trio can easily pen a worthy tune and, on the back of the huge support last year for its lead track, 'Heartbeat Overdrive', they knuckled down to write and record their first full-length album, The Dew Lasts An Hour, which serves as a potent soundtrack to summer's transition into autumn.

The 405 bombarded Collet with questions about each and every track on the record, which we've collated into this listening guide.

The Dew Lasts An Hour opens with 'Slow Dream' and - as the title suggests - it provides a rather dreamy, moody start for the record. "It was part of my sound alchemy, which we decided to add to the album", Collet states mysteriously. But the first song purposefully written for the record was the thunderous 'Pale Saint'. Collet had had the riff swimming in his head for a long time before Blair eventually turned it into a song. "We thought we needed another power song for the album. We were very happy when we got it," Collet explains. The title itself betrays the band's admiration for the 4AD rockers, Pale Saints. "Yeah, we're fans. They're great. We love listening to them."

The band have re-worked the tracks from Boys Again, which now appear in a new guise on the album. "We wanted all the songs on the album to have same production values and sound coherent. The tracks on Boys Again were produced and released in a short period of time after we got signed to Bella Union. I think the songs were still developing as we were playing them live," Collet says.

One of those songs is 'Ghost', which is also the first track Ballet School originally put on their Bandcamp page back in November 2012. The 405 asks whether this was the song that brought about their Bella Union deal. "The song that got us contacted by Bella was actually the video for 'All Things Return At Night'," Collet clarifies. "What got us signed after months of flirting was a live gig in Dalston's venue, Birthdays, in May last year. Back then when we wrote the song, Louis was not in the band. We had a bass player and he called Rosie and me one morning saying 'we need a fast song'. I remember feeling the song's fast beat immediately in my chest. 'Ghost' together with 'Heartbeat Overdrive' were a turning point, where we knew the direction we wanted to take our music."

Next comes 'Heliconia'. The title references the tropical plant, with a nod to Collet's homeland of Brazil, where he spent a lot of time in heliconia jungles. "Much of my guitar sound is drawn from a tropical interpretation of shoegaze," he explains. "Swarming insect symphonies, roaring waterfalls, white water lilies' perfume in dusk. The production is supposed to evoke this synesthetic and tropical lush. Rosie and I wrote the song but everything changed once Louis added the half-tempo beat."

Ballet School recently released the video for current single, 'LUX'. The song is a sumptuous, nuanced mid-tempo number and the video, directed by Nova Dando, complements it beautifully. "Nova is an old time mate of Rosie's," Collet says. "They went to art school at Saint Martins back in the day. They are a tight crew. Nova is an amazing personality and the set of the video shoot was ultra professional." The 405 rather fell for the cat in the video. "Oh that baby cat will forever stay a kitten in our hearts," Collet gushes.

With 'Gray' you get the most contemporary-sounding beats and drum-fills on an otherwise predominantly '80s-influenced record. The 405 asks Collet how conscious the band was of such sonic influences when arranging and producing the songs on the album. "We were all born in the '80s. The sound of reverb gated snare is really comforting for us. But we have no intention of merely being an '80s band. It's just a starting point to push pop music forward," he explains.

'Heartbeat Overdrive', which Collet mentions earlier, is the big banger on the album and made for a sweeping "proper" debut single last year. The album version comes complete with a new intro. "Last year we released a 12" with an extended mix of the song and the album version is an edit of that extended track with some new guitars and overdubs," Collet explains. Did the band feel it was the obvious calling card single for them when they first record it? "Yeah, we knew it was good," Collet says assuredly.

Alongside 'Heartbeat Overdrive', the track 'Cherish' sits as another strong chorus provider on the album. The 405 asks Collet what comes first for him when writing a new song - a verse or a chorus? "The writing process for most of our songs on the album started with me playing the guitar until Rosie would say 'yeah' and hear a melody in there," he explains. "We then develop things from that sound that inspired us and Rosie would write the lyrics in solitude. 'Cherish' is a good example of this process. It started with verses and the chorus came quite naturally with a chord change, although the guitar and drum sounds were actually particularly hard to nail."

Shedding more light on their creative process, Collet says: "Rosie is responsible for structuring the songs into pop. We produce a demo with most of the elements that will be on the final version and then we give it to Louis to develop the beat. In the rehearsal room we try the songs out and see if they have a good drive to them."

Breaking from that norm, however, Blair wrote next track, 'Jade', without any involvement from the other two. "Lyrics, melody, guitar, beats and everything," Collet says. "Which is why I cannot give a full insight to this song, I'm afraid. I remember being half-asleep hearing Rosie playing guitar and singing as she was writing the song in the other room. It was really dreamy."

As Collet explains earlier, the original version of 'All Things Return At Night' heralded the band's record deal. The album re-interpretation fits in more with the general sound of the rest of the record. "We like both versions," Collet says. "The first version was played entirely live, with no overdubs, with Whitest Boy Alive's drummer, Sebastian Maschat. It was fun to do. But I think we never really nailed the production first envisioned by Rosie, who wrote the song. It was meant to be more Smithsy."

'Yaoi' is another revisited Boys Again cut. "We thought that the tempo on 'Yaoi' was a bit too fast," Collet says. "But overall, we just added more colors to it. We wanted to make them more beautiful". When The 405 asks whether the song, as the title suggests, is all about manga homoerotica, Collet directs us to Blair's tumblr entry on it, which is rather self-explanatory.

'Crush', almost unrecognisably transformed from its Boys Again original version, sounds a bit more like a torch song on the album. The 405 asks why the three decided to change it so drastically. "The chords on album version are actually closer to the very first version of the song that Rosie wrote on guitar years ago, when she was still living in Belfast," Collet clarifies. "The album version started as an R&B merry jam in the rehearsal room when Louis joined the band."

Fans who splash out on the iTunes deluxe version of the album will get a few extra tracks including the band's earliest songs from their 2012 release, Softer. "'Sara' is the same version as the Soundcloud version but 'Day Off School' has a great new production that Louis worked on. Turned out to be a great song to be played over Christmas time," Collet tells us. Do Collet, Blair and McGuire still play these golden oldies in their live set every now and again? "We play 'Sara' sometimes at the end of the show if the audience is nice."

Finally, a track called 'Boys Again' appears on the deluxe format of the album as well. The 405 asks why it wasn't, in fact, included on the Boys Again EP. "This song was actually originally meant to be part of a full album that we never released called La Luna," Collet reveals.

So there you have it.

The Dew Lasts An Hour is out on 8 September on Bella Union.
