Not only will they be the only attendees at any Falls this year to hear the sounds of The Rubens, but they will be one of the first to hear new material from the New South Welshman ahead of the release of their long-awaited second album next year.

"[Playing at just Marion Bay] means we will get to put all our effort into playing just this one show," keyboarder and backing vocalist Elliot Margin said.

"We've only recently come back from New York working on and recording the new album, so we'll be treating it [Falls] as a bit of a test, as we are really excited to be playing new songs and thinking about new sets, so it will be a special one.

"I think our new stuff is a lot more mature, as we spent a lot of time writing in different places.

"We wanted to write songs that we would be really excited to play, that we think people would be excited to hear, and that would have a lot more energy for the live show.

"We think that comes out in the songs that we have at the moment."

Margin said the boys had purposely taken their time since their debut in 2012.

"People often say there is a lot of pressure for the second album, and I wouldn't say we felt any pressure, but we know it is something that people look for - looking for you to trip up on your second album.

"So we thought we would relax, as we know what we like in our songs, and not rush anything and make sure we do it right.

"We've been sitting on a lot of material for a long time, and hopefully by the time the album does come out people are itching for it."

Margin, who said it was still "crazy" to think how much the band had achieved in such a short time, said that despite the new material, the high-energy feel would still be there at Marion Bay.

"If anything there will be more energy," he said.

"With the first album we knew how to write songs, but we never really thought about the live show, to being on stage and playing in front of people.

"All of a sudden last time we were playing in front of people having to amp it up because of this.

"Now that we have done that, we have amped it up more for people energy wise, with hooks for people to look out for, which actually made the writing process more fun thinking about the live show as we did it."
