Infrasound

Infrasound (Infrasound Equinox) is an intimate bass- and electronic-music festival at Harmony Park Music Garden in Clarks Grove, Minnesota, known for its heavy dubstep and bass programming and an obsessively good sound system. It runs multiple stages plus an all-night silent disco, keeps crowds small and unhurried, and enforces quiet hours so campers can actually sleep, cultivating a tight-knit, returning community that treats it as a home festival rather than a commercial event.

Infrasound runs Thursday to Sunday, May 13 to 16, 2027, with three nights of music and art at Harmony Park Music Garden. It is a camping festival: most people leave the car in a designated lot and walk their gear into the campground, and only holders of the car-camping pass bring a vehicle in. Music plays across several stages, and because the park enforces strict cutoffs for amplified sound, the late hours belong to an all-night silent disco.

It suits bass-music fans who want a small, camping-focused festival with a close-knit crowd and a real night's sleep. It is an 18-plus event with no dogs and firm quiet hours, so it is less suited to anyone who wants a camp party that runs all night or who plans to bring a pet.

Attendees repeatedly rank Infrasound among the best festivals they have been to, singling out the sound system and consistently strong lineups, the relaxed, non-packed stages and low-key security, and the rare ability to get good sleep thanks to enforced quiet hours. The all-night silent disco is a recurring highlight, and many describe a warm, familiar community that returns year after year.

In a recent edition, attendees noted that first-day rain affected some sets before conditions improved across the weekend, a pattern regulars treat as part of the outdoor Harmony Park experience. The lineup and sound production again drew strong praise, consistent with the festival's reputation for punching well above its small size.
