Lead singer Blaine Harrison says of the song;
"Screwdriver is about the mechanics of intolerance.
"Looking back at times of economic instability in history, we see how easily deep chasms grow in society and the population seeks change wherever it is most convincingly promised.
"Conflict arises as cultures and belief systems clash, unwilling to accept one another's place in society, because we are fed the rhetoric that our neighbours are those responsible for our problems: then inevitably nationalism once more raises its ugly head above the parapet.
"But whereas political agendas fuel divisiveness, music unites and reminds us of all that we have in common.
"The message of Screwdriver is not a pessimistic one - because perhaps faced with confrontation we can find understanding, and even maybe learn how to listen to, and love one another."
All great albums start from a unique perspective.
But, try a window on the Strand, in an abandoned office block, overlooking the kind of political upheaval London hasn't seen in a generation.
Blaine Harrison was living as a property guardian right around the corner from Trafalgar Square when he found himself witness to an entire year of protests.
Every weekend from January 2017 on, people were marching for a different cause:
"In the space of six months it was Black Lives Matter, the huge 'Our NHS' march, Unite for Europe," he recalls.
"Then the solidarity sleep-out organised by Help Refugees, where we slept in Whitehall for the night... The protestors would wake me up in the morning. I'd just walk down and join in."
Over the course of that year, Mystery Jets' sixth long-player, A Billion Heartbeats, was born.
"This album wasn't about making pointed opinions," says Blaine.
"It was about being a mirror for what's going on, reflecting back the way people are feeling."
We increasingly hear from musicians that music should be an escape these days - that there's enough suffering in the world, enough misery on the news, without writings songs about it too.
A Billion Heartbeats makes all that sound like a bit of a cop-out.
These are songs of protest that get the heart racing in joy; high on hope, and serious in their message. Proof, basically, that music speaks louder than words.
Mystery Jets will be performing and signing
copies of the new album at Brighton Resident
on 1st October 2019.
