As December Falls have released a new track titled "Nervous" featuring guest vocalist Markus Videsäte from Swedish rock band Solence, marking the band's first-ever artist collaboration on a recording. The song is a catchy pop-punk track that alternates between atmospheric and energetic moments, delivering what vocalist Bethany Hunter describes as an exploration of the nervous, butterflies-in-stomach feeling one experiences around someone special.

The track was written whilst the band were on the road and developed through back-and-forth collaboration with Videsäte, who performs the second verse and returns for the final chorus. Hunter noted the band were particularly pleased with the guest vocalist's performance, with "Nervous" following the band's previous releases "Teeth" and "Anymore" in their recent catalogue.
