"Heartbursts" lands with a Teresa "Toogie" Barcelo-directed video, and will feature onn Second Nature with previous singles "White Lies" and "Next To Normal".

Jess Wolfe says of the song and video, "We’ve been wanting to work with Toogie for years after seeing her dynamic work with a diverse cast of artists from Perfume Genius to Dua Lipa. Because the song is about finding your joy and tapping into it, we thought what better way to emphasise that than with a group of people in their everyday life moments, breaking out with movement. We really wanted the video to convey the way the song feels when we hear it, and as a team, it really came to life."

Second Nature is produced by Dave Cobb and Brandi Carlile, and will follow their 2018 album Nudes. It was recorded at Nashville's RCA Studio A, and includes additional contributions from Carlile, Sheryl Crow, Drew Erickson, Rob Moose and Gabriel Cabezas.

"Heartbursts" is out now. Lucius' Second Nature album will arrive on 8 April, and is available to pre-order now.
