Mixing & Mastering Engineers, Producers & Songwriters who worked with Bill O'Hanlon
I’m a singer/songwriter influenced session vocalist with 10+ years of singing experience. I specialize in raw tuning accuracy, tight vocal stacking, and emotionally driven performances that bring songs to life. My goal is to deliver vocal stems that sound as polished as possible on their own, so you spend less time editing and more time producing.
