The all-singing, all-dancing Pitch Perfect 2 is out in cinemas on May 15, so we headed to meet the Dublin a capella band the Trinitones to find out a little bit more about the world of a capella.

We chatted to band-members Declan and Robert about how their group started, if their are any egos in the band and what it was like competing in the ICCAs, the international a capella singing competition shown in the film.

The group have a penchant for pop covers and scored a YouTube hit with their brilliant cover of Teenage Dirtbag, we also got a hint of what their next video might be.

Pitch Perfect 2 hits cinemas on May 15.

Read a synopsis of the movie below:

The Barden Bellas are back to pitch slap the world in Pitch Perfect 2, the follow-up to the original runaway global hit about a group of lovable misfits with only one thing in common: the irresistible way they sound when they’re seamlessly mixed together, mashed-up and arranged like never before.

It’s been three years since the Bellas brought their signature vocals, style and attitude to become the first all-female group to win a national title.  But when they get banned after a scandal that threatens to derail their last year at Barden, the three-time defending champs worry that this time they’ve lost their harmony for good.

With just one chance left at redeeming their legacy, the Bellas must fight for their right to win the World Championships of A Cappella in Copenhagen.  And as they struggle to balance the pressures of musical domination with senior angst, it will take the power of sisterhood to find their voice and see what it takes to be the world’s top pitches.
