Mercury Mine Monster is a music and arts festival, but it’s more than just a festival—it is a co-created experience, a living experiment in radical creativity, immersive art, and shared expression, set in the heart of Russian River, CA.

At MMM, there are no spectators—everyone plays a role. Whether by building, performing, crafting, or volunteering, each participant contributes to the magic. We believe in the power of shared investment—when everyone brings something to the table, we create an experience that exceeds what any one of us could build alone.

MMM is built by the community, for the community. It is a place where visionaries, artists, makers, and dreamers push creative boundaries, where bold ideas take shape, and where the act of gathering itself becomes an art form.
