Breakout four-piece SLEEP THEORY has unveiled the official music video for their song 'Words Are Worthless'.

The track is taken from the band's debut album, 'Afterglow', which came out May 15 via Epitaph.

Produced by David Cowell and mixed by Zakk Cervini, 'Afterglow' boasts over 515 million global streams to date.

SLEEP THEORY has toured extensively since their formation, selling out most of their headline dates and performing at various festivals.

Their music combines energetic hard rock and metalcore with powerful vocals courtesy of vocalist Cullen Moore.

Praised by Jelly Roll and DISTURBED's David Draiman, the band has gained significant attention in under two years, becoming one of heavy music's biggest breakouts.

The 'Paper Hearts' EP, alongside their debut album, merge heavy rock with pop and R&B elements to create anthemic bangers and emotional ballads.
