ENDIT is thrilled to welcome STS9 back to the historic Boulder Theater on Friday, August 29, 2025—marking the band’s first appearance in the room in ten years and a rare chance to catch their genre-blurring, high-energy live show up close before their Dillon Amphitheater weekend. Doors open at 8:00 p.m., and the music lifts off at 9:00 p.m. This is an all ages performance (patrons under 16 must be accompanied by an adult). Both General Admission and Reserved Seated tickets will be available.
A special limited early purchase window has been set aside for fans who buy tickets to STS9’s Dillon Amphitheater shows (August 30 & 31) by 12:00 a.m. MT on Friday, July 18. Eligible Dillon ticket holders will receive a password via email granting access to purchase Boulder Theater tickets ahead of the public on-sale. (Important: Having a Dillon ticket does not guarantee admission to the Boulder Theater date—capacity is limited and tickets are first-come, first-served once the presale opens.)
The public on-sale begins Friday, July 25 at 2:00 p.m. MT. Purchase directly: https://www.z2ent.com/events/detail/sts9-2025-bt. Additional venue and show details: www.bouldertheater.com.
Beloved for weaving live improvisation with electronic grooves, richly textured instrumentation, and immersive production, STS9 has cultivated one of the most dedicated fan communities in the improvisational and livetronica worlds—nowhere more passionately than in Colorado. With the intimacy of the Boulder Theater and the momentum of a holiday-weekend Front Range run, this one is primed to sell fast. Secure your Dillon tickets now if you want in on the presale—and be ready when the public on-sale hits.
