After three EPs and touring internationally with the likes of Sum 41, Simple Plan and Movements, Eat Your Heart Out have done some serious growing up.

Florescence, released last Friday, is a mature effort from a rapidly developing band and a further endorsement why the five-piece is considered the next Newcastle band to breakout internationally.

"We wanted to feel like we'd taken a step forward and matured our sound and explored some things we hadn't before by adding more dynamics in the songs and the album as a whole," vocalist Caitlin Henry said.

"We wanted to make it the most personal thing we've ever done in terms of the lyrics. That was definitely our goal; to step up as a band and mature a little bit."

Florescence was recorded in December and January in Los Angeles where Henry, Andrew Anderson (guitar), Will Moore (guitar), Dom Cant (bass) and Jake Cronin (drums) bonded further by celebrating Christmas together away from their families in their Airbnb.

While most of the music was written before heading into the studio, the majority of Henry's lyrics and melodies were developed in LA.

"It was very stressful obviously, but it worked out really well writing most of it in the studio because it meant everything I wrote lyrics about was fresh and relevant," she said.

"It wasn't old stuff that happened two years ago. It was stuff I was still going through or feeling at the time. It meant we were on a tight schedule and we didn't have time to question much or cast too much doubt."

Closer To The Sun and Blinded showcase Eat Your Heart Out's departure from pop-punk towards an anthemic rock sound, while the acoustic Pear Tree is their most vulnerable song to date.

"It's about a dog Will [Moore] had as a teenager, which he had to bury in the backyard," Henry said. "It's a really heavy thing that goes along with that theme of growing up and they're things you have to deal with once you're an adult."
