Read this: Strength in unity: Why IDLES will never give up the fight
"We wanted to write a song that embodied self-belief, and gave us self-belief – a counter-punch to all the doubt we build up from all the noise we so easily let in," explains frontman Joe Talbot.
"We wanted to make the sound of our own hearts’ marching band, armed with a jack hammer and a smile. We wanted to make the sound of our engine starting. So we did. Thank you."
Ultra Mono is due out on September 25 via Partisan Records, with IDLES confirming several unique livestreams in the run-up to the release. You can get your tickets for those right here.
