Starring Ferdia Walsh-Peelo, Lucy Boynton, Maria Doyle Kennedy, Aidan Gillen, Jack Reynor and Kelly Thornton, the story revolves around a boy starting a band to impress a girl in 1980s Ireland.

Living in inner-city south Dublin in 1985, Conor Lalor's dad Robert[9] struggles with his architecture practice and his marriage, and drinks and smokes to excess.

At a family meeting, he announces he is taking the youngest son Conor out of his expensive school and moving him to a Christian Brothers one, Synge Street CBS, which Robert asserts is of equally high repute.

When Conor recruits aspiring model Raphina for a music video, Darren agrees to manage his band and introduces him to multi-instrumentalist Eamon.

The band films their first music video wearing comical costumes; Raphina acts as ingénue and makeup artist.

Conor strikes up a friendship with Barry, offering him the chance to be the band's roadie and escape his abusive family.

After secretly saying goodbye to his family later that night, Conor and Raphina persuade Brendan to drive them to Dalkey, so they can escape in the motor cruiser and head to London.

Brendan watches them disappear into the distance and cheers, overjoyed that his younger brother has left to go on to greater things.

In February 2014, it was announced that John Carney would be directing the film, from a screenplay he wrote about a boy starting a band in order to impress a girl.

[12][13] The unknown actors turned out to be Ferdia Walsh-Peelo, Ben Carolan, Mark McKenna, Percy Chamburuka, Conor Hamilton, Karl Rice, and Ian Kenny.

[14] In September 2014, it was announced that Aidan Gillen, Maria Doyle Kennedy and Jack Reynor had joined the cast of the film, portraying the role of Conor's father, mother and brother respectively.

The website's critical consensus reads, "Sing Street is a feel-good musical with huge heart and irresistible optimism, and its charming cast and hummable tunes help to elevate its familiar plotting.

[33] Guy Lodge of Variety.com gave the film a positive review, writing "Perched on a tricky precipice between chippy kitchen-sink realism and lush wish-fulfilment fantasy, this mini-Commitments gets away with even its cutesiest indulgences thanks to a wholly lovable ensemble of young Irish talent and the tightest pop tunes—riffing on Duran Duran and the Cure with equal abandon and affection—any gaggle of Catholic schoolboys could hope to write themselves.

"[36] In The Observer, Mark Kermode gave the film four out of five stars, writing: "When it comes to capturing the strange, romantic magic of making music, few modern film-makers are more on the money than John Carney."

He added, "The bittersweet, 'happy sad' drama that follows has drawn inevitable, if misguided, comparisons with The Commitments, yet tonally this is closer to the teen spirit of Todd Graff's 2009 film Bandslam...or even Richard Linklater’s sublime School of Rock.

As Carney has proved previously, he knows how to straddle the line between the sound in the room and the sound in your head – a sequence that segues from bedroom composition to living room rehearsal (with tea and biscuits) to full studio production perfectly negotiates the space between kitchen-sink realism and musical fantasy in which this lovely, lyrical movie casts its spell".
