In September 2013, three game-changing debut albums were released. Lorde table-flipped pop music with Pure Heroine; Haim pulled 80s rock nostalgia back into the charts with Days Are Gone; but before either of those records, London Grammar released their debut album If You Wait - a sublimely intricate cocktail of
London Grammar on second-album nerves and learning their limits

Despite the four-year gap between albums, the move from If You Wait to Truth was a constant, continual process for London Grammar. The trio toured their debut right through to early 2015, at which point Reid wrote Truth's first single Rooting for You "in its most primordial form," says Rothman; they then worked on the album over two years up until March 2017.
The experimentation that Rothman refers to is evident throughout Truth is a Beautiful Thing. The melancholic sensibilities of their debut are back, but this time there's a newfound cinematic grandeur that lifts their songwriting to new heights. Songs such as Big Picture and Hell to the Liars build from flickering candles into explosive climaxes; layers of synths, guitars, vocal harmonies and percussion snowball into illuminating crescendos - a sound Rothman says was prompted by their live shows.
"That part of the album making process was actually quite organic. [Those songs] were a natural reaction from being on tour - we would do these elongated outros to some of the songs and we felt that we wanted to have that on some of the new music," he says.
"It definitely caused some level of debate between the three of us when we were doing it, because sometimes it felt like if you try and tack an ending onto a song it doesn't necessarily flow particularly well. With Hell to the Liars, it was even more climactic than it currently is and it was almost a bit over the top. We had to rein it in a bit because we were worried we were forcing it too much."
London Grammar are currently in the midst of a global tour, which has so far seen them play across North America and Europe. The trio were on the road shortly after Truth's release, and Rothman says there wasn't much time to reflect on the release of the record. Rather, they faced the more immediate and practical challenge of learning how to play the newer, more muscular material live.
"There are more layers of instrumentation, which means we've had to take it a step further with regards to the way we play certain parts. It becomes more convoluted in that sense and that's just got even more severe with this record.
"Hannah as a result has had to step in more - she's playing more piano on certain songs, which has been really positive. It's been a good process. I've been pleasantly surprised at how well [the new songs] have slotted into the set."

London Grammar's Spark Arena show will be their first ever in New Zealand, which Rothman says they're "incredibly excited" about. And with a set that mixes the sinewy new material with the lilting rhythms of their debut, Kiwi fans can expect to be hypnotised - and exhilarated.
