Slayer is commemorating the 40th anniversary of their seminal album 'Reign in Blood' with a limited-edition liquid-filled vinyl release and a full-performance tribute at the 2026 ROCKLAHOMA Festival. The band's legacy continues to influence new artists and receive scholarly attention, as evidenced by an upcoming book on Metallica, Anthrax, Slayer, and Megadeth, while related projects like OV SULFUR's cover of 'Disciple' and Satanic Planet's new music highlight ongoing cultural resonance.
