Hi, I'm Glenn Erwin — a Los Angeles-based mixing and mastering engineer with credits including Rihanna's Loud Tour Live at the O2 Arena (Blu-ray release).
For over two decades, I've worked in high-pressure environments: arena tours (Cher, Madonna, Michael Jackson ONE, Maxwell), residencies (Caesars Palace), and elite studios. This experience shaped my approach: masters that sound massive yet musical, warm yet punchy, with real dynamics at -10 LUFS (streaming sweet spot) — no squashed life, just impact.
I specialize in electronic, dance, pop, and hybrid genres. My custom analog-emulation chain (EMERALD 2BUS) delivers deeper lows, tighter transients, and subtle clarity with minimal moves.
Whether you're an artist, producer, or label needing a competitive master that stands out on Spotify/Apple/YouTube, let's make your music sound like it belongs on the biggest stages.
