On January 24, 2020, during an interview for
People TV on the red carpet of the
MusiCares Person of the Year ceremony, Cantrell announced that he was working on a solo album. He started recording at Dave's Room Recording Studio in
North Hollywood, Los Angeles on March 10, 2020. On March 4, 2021, Cantrell announced via his
Instagram page that he had completed the album, captioning the photo: "Finished my record tonight one year to the day from when we started recording it. What a crazy journey... always is. Look forward to setting it free upon your ear holes sometime soon." Producer Tyler Bates previously worked with Cantrell on the song "
A Job to Do", featured on the soundtrack to the 2017 film
John Wick: Chapter 2, and on the song "
Setting Sun", written for the soundtrack of
DC Comics' graphic novel
Dark Nights: Metal. Bates helped put a band together for Cantrell's solo concerts at the Pico Union Project in Los Angeles on December 6 and 7, 2019, and some of those musicians are also featured on
Brighten, such as
Greg Puciato,
Gil Sharone, Jordan Lewis and Michael Rozon. Drummer Gil Sharone had worked with Cantrell on "A Job to Do" and "Setting Sun". Cantrell originally intended to release
Brighten in September 2020, but had to postpone it due to the
COVID-19 pandemic. Due to the COVID-19 restrictions and lockdown, Laboriel Jr. couldn't travel to
Los Angeles to record the tracks, so recorded his drum tracks in New York where he was locked down. Cantrell originally wanted
Tom Petty and the Heartbreakers's keyboardist
Benmont Tench to play keyboards on "Siren Song". Tench was interested in playing in the song, but something happened and he couldn't do it, so
Vincent Jones ended up replacing him. On June 29, 2021, after low quality photos were leaked from a music video shoot, it was reported that
Guns N' Roses' bassist
Duff McKagan would be featured on Cantrell's new solo album. Cantrell confirmed McKagan's collaboration the next day by posting higher quality behind-the-scenes photos from the music video shoot that also showed Gil Sharone on drums and Greg Puciato on guitar and vocals on the set. == Music and lyrics ==
