William joins Matt to talk about "Black Horizon," his debut with Metal Allegiance and the first new music from the hard rock supergroup in eight years. We also discuss his experience working with Metal Allegiance founder Mark Menghi in King Ultramega and their explosive cover of Soundgarden's "Rusty Cage." Plus, William gives us the origin story of how he met and started touring with Jerry Cantrell as part of Jerry's solo band for the Degradation Trip album (before the album was even out!). He also shares a surprising anecdote about his early days in Alice in Chains.
