Ahead of the release of her upcoming album, the sum of the in-between, Maria Kelly has shared the highly anticipated project's title track.

‘the sum of the in-between’ is the fourth single from the record, out on October 15, on the artist-led independent label Veta Music. The new song features Maria Kelly taking an honest look at herself and accepting what she sees.

The expressive single features a tinkling piano, galloping strings and a steady guitar that lay beneath Kelly’s vocals and a soaring solo violin: “Who I was, who I’ll be / I’m the sum of the in-between,” she sings in the outro.

“‘the sum of the in-between’ is a long list, laying out every messy, chaotic, complicated thing about me," says the alt-folk star. "It’s about giving myself permission to look directly at this current version of myself without criticising everything I find.

“For me, that’s what this album is about – permission," she adds. "Permission to face myself, permission to feel it all, permission to get the help I deserve – no matter how uncomfortable or painful that might be."

Kelly has been building excitement for the release of her debut album with a number of singles. Lead single ‘Martha’ dropped in April and was shortly followed by ‘eight hours’ in May. Her last single ‘good enough’ arrived in June.

The three singles “are deeply introspective and honest songs about her own mental health journey and the rest of the songs on this album, including this new single, continue that exploration."

The singer is also gearing up for a headline show in Workman’s to celebrate the release of the album on November 12th. Tickets for the event are available on Ticketmaster for €15.

The Mayo-born, Dublin-based star recorded the album during lockdown after retreating to a cottage away from the city. The upcoming album is being touted as one of the most exciting independent Irish releases this year.
