"Shockwave" is Gallagher's first single since his 2017 debut solo album As You Were.

Speaking about his return to music, Gallagher said, "I’m buzzing. Buzzing to be alive, buzzing to be making tunes, raring to go. It’s nice to be back with some new music because it means I can get out there, play some gigs and give some people some stick because that is what I do. Let’s face it, it’s boring without me."

The new single coincides with the release of his new film, Liam Gallagher: As It Was.
