Powerflo fuses hiphop, heavy metal, punk and rock together – and honors their name! Billy Graziadei describes Powerflo as “a mix between Iron Maiden, Black Sabbath and Cypress Hill”. The band is the brainchild of Biohazard’s guitarist/singer Graziadei, ex-Fear Factory’s bassist/guitarist Christian Olde Wolbers, “worst” drummer Fernando Schaefer, ex-Downset guitarist Rogelio Lozano and Cypress Hill’s rapper Sen Dog.
