Set to premiere on streaming major streaming services including Apple TV and Prime Video November 11th, 'Blood 4 Blood: Sound of War' is a new documentary film that examines Alex Terrible's ambitious bridge of heavy metal and bare knuckle boxing. Earlier this year, the Slaughter to Prevail frontman merged his words of combat sports and deathcore with the launch of his Blood 4 Blood event in partnership with Danny Wimmer Presents. 

Combining a well-curated line-up that saw Terrible pulling double duty, Blood 4 Blood featured live performances from Slaughter to Prevail along with Black Label Society, Crowbar and Malevolence. Blood 4 Blood also featured hard-hitting action inside the squared circle with bouts headlined by Alex Terrible facing off against Cameron Delano. 

While the event ultimately saw Terrible get bested in a three round slugfest, the innovative event proved a resounding success for Terrible - who set out to bridge tow subcultures and found a thriving intersection that filled the seats inside the Ocean Center  in Daytona Beach, FL earlier this spring. 

Along with behind-the-scene footage and testimonial footage, the film features guest appearances from the likes of Zakk Wylde, BKFC superstar "Brutal Chad Bostwick, BKFC Champion Mohawk Rodriguez, metal music ambassador Jose Mangin and Slaughter to Prevail guitarist Jack Simmons.
