The unmistakable voice of metal race-machine V8, Alberto Zamarbide embraced the role of frontman in the middle of social and political chaos in his native country, Argentina, during the early eighties. By the 1990s, after leaving V8, Zamarbide formed the band LOGOS and released five powerful albums. The second album, Generación Mutante, was produced by Rudy Sarzo, the premiere bass player for heavy metal bands Quiet Riot, Ozzy Osbourne and Ronnie J. Dio. The years that followed were spent touring and opening for acts like Kiss, Monsters of Rock, and Megadeth, among many others. By 2007, LOGOS recorded their live album and DVD using Audix microphones on their entire setup.
In 2013, Zamarbide celebrated the 30th anniversary of his iconic first LP with V8, "Fighting for Metal." After the release of his documentary Relampago en la Oscuridad (Lightning in the Dark), by 2014 Zamarbide returned and formed a new unit, Primal, with former members of Hirax Jorge Iacobellis (drums) and Dave Watson (guitar), bassist Sandy Vasquez and Wagner Vincenzi on guitar. Near the end of 2016, they released a new self-titled studio album.
Primal studio engineer and GRAMMY winner Iggy Elisavetsky uses Audix mics at D-Organization Studios (Sherman Oaks, CA) and on stage. The OM5 is used to give Zamarbide more gain before feedback in his wedges and side-fills. "When he switched over to Audix from the BETA58 he'd been using for years, he found an incredible difference. Alberto achieved more high-end response in his vocals while finding it easier to hear himself in front of the amps."
