In March 2020, when interviewed by Guitar World about his endorsement with Dean Guitars, King hinted that he would be working on new material for his first project since Slayer's disbandment, simply saying, "Dean didn't sign me for nothing!"
King stated in an August 2020 interview on the Dean Guitars YouTube channel that he had "more than two records' worth of music".
It was later confirmed that he and former Slayer bandmate Paul Bostaph were working on a new project that would "sound like Slayer without it being Slayer — but not intentionally so."
In November 2023, King hinted that he was going to release the debut album by his new project in 2024; this project was later revealed to be his solo debut album, "From Hell I Rise", due for release on May 17, 2024. The lineup on the album includes King, Bostaph, Death Angel vocalist Mark Osegueda, Hellyeah bassist Kyle Sanders, and Vio-lence and former Machine Head guitarist Phil Demmel.
