On Sunday (27 June) Big Red Machine started teasing something called How Long Do You Think It's Gonna Last?. The clip featured layered, multi-coloured visuals with both Vernon and Dessner, and fans also claimed that Taylor Swift and her handwriting were in the teaser too.

While Big Red Machine are yet to announce exactly what How Long Do You Think It's Gonna Last? is, it does seem more likely that it could be their upcoming album/project than a single, as the duo shared another four teaser clips yesterday (28 June) with different snippets of music.

Their latest teaser is a three-second clip that doesn't feature any music, but does appear to confirm Swift's involvement as it shows star turning her head to lookk at the camera (although her face is blurred).

As well as seeming to confirm Swift's involvement, fans also think Sharon Van Etten might be appearing on the project in some way, as she also took to social media yesterday (28 June) to share a teaser, writing, "It’s coming…"

Vernon and Dessner contributed a cover of Sharon Van Etten's "A Crime" to her epic Ten album earlier this year, and both worked on Swift's 2020 albums Evermore and Folklore.

Big Red Machine are yet to reveal exactly what How Long Do You Think It's Gonna Last? is, but it looks like an announcement could be coming this week.
