About Us

⸻

For over 40 years, GCS Audio has been a trusted name in live sound and event production throughout Detroit and the Midwest. What began as a small, passionate operation has grown into a full-service production company supporting concerts, festivals, venues, corporate events, and community gatherings of every size. Our longevity comes from a simple promise: deliver clear, powerful, and reliable sound every time, backed by crews who understand that every event matters. From outdoor city festivals to intimate venue shows, GCS Audio has helped shape the sound of countless performances across the region.

At the heart of GCS Audio’s legacy is Steve Marshall, whose dedication, technical expertise, and commitment to excellence laid the foundation for everything we do today. Steve believed that great audio isn’t just about equipment — it’s about craftsmanship, preparation, and respect for both the artist and the audience. That philosophy continues to guide our team as we invest in better systems, stronger processes, and the next generation of engineers. We are proud to carry forward the standard he set, ensuring every event we support lives up to the reputation built over four decades of service.
