MAGNITUDE -The Saturday Night Main Event of Folsom Street Fair™ After last year’s steamy, sold-out event, Folsom Street and Brian Kent Productions return with the 42nd Annual MAGNITUDE—the Main Saturday Night Event of Folsom Street Fair™—and this year, we’re going deeper, darker, and hotter than ever before. On Saturday, September 27th at 9:00PM, enter the pulse-pounding heart of SVN West, reimagined as a massive, industrial steam room. With fog curling through the air, walls vibrating with bass, and light slicing through mist, this is a night built for the bold. Let the haze guide you through the dance floor, immersive lighting, and jaw-dropping performances from some of the most captivating artists in the scene. Three legendary DJs will take command of the sound, building an atmosphere thick with rhythm, tension, and release—keeping you moving deep into the night. Magnitude 2025 is more than a party—it’s a visceral, high-energy experience designed to ignite the senses and celebrate the spirit of Folsom. Get lost in the steam. Let the night consume you.
