The guitarist told Billboard that he's "at the very tail end of the demo phase" for the solo project, which he hopes to start recording early next year.
He began creating material during Velvet Revolver's last tour and said that while it will have references to his work with that band and Guns N' Roses, "there's really no particular direction. I just wanted to take a little bit of a break from all the politics and the democracy that is a band and just sort of do my own thing for a little bit. There will be a lot of stuff I don't have the freedom to do in a band situation."
