Overview Freakfest is a Halloween rave inside City Museum in downtown St. Louis, the artist-built playground of tunnels, caves, slides and climbers that the sculptor Bob Cassilly and his crew built into a former shoe warehouse. Disco Presents puts it on with Brown and White Productions as one night, 18 and over, with doors at 7:30; in 2025 it fell on Halloween itself and in 2024 on the Sunday before. Disco Presents was founded in 1994 by James "Disco" Donnie Estopinal, says it has sold more than 25 million tickets across more than 21,000 events, and promotes close to 1,000 club nights a year in cities that include St. Louis. Its festivals include Lights All Night, Ubbi Dubbi and Freaky Deaky. Talent and Influencers The Crystal Method headlined 2025 on a bill with LP Giobbi, Deathpact, Ghengar and Figure. Dombresky, Barclay Crenshaw, MitiS and Mark Farina played the 2024 night, and Claude VonStroke, Of The Trees and Spencer Brown topped the 2022 lineup. Track record Freakfest was already a returning Halloween night when Disco Presents billed its 2021 edition "A Night at the Museum" at City Museum, and it came back to the building for 2022, 2023, 2024 and 2025. Partnerships on the listing run in four levels, from a title or presenting partner down to a supporting or community partner.
