"December" is the third single to be shared from Everything At Once, after "Two Sense" and "Lennox Hill".

According to Stereogum, vocalist Millie Duthie wrote the song for her sister. She says, "It came from a really dark and desperate place. But the song manages to put into words what she could never say."

The band's Everything At Once EP will follow on from their debut EP What’s On Your Mind.

Thyla's new single "December" is out now. Their Everything At Once EP arrives 24 January 2020.
