ONSET presents BLKHRT · Cleveland Heights · Oct 25, 2026

Sunday, October 25 ONSET: BLKHRT at Grog Shop and B Side Lounge Featuring DJs ZOMI3 / POIZON / ZANE $100 Best Costume / $200 Best Couples Costume Doors 8 PM | Show 8 PM - 1 AM AGES 18+ $10 Limited Early Bird | $12 GA in Advance | $15 Day of Show +$5 at the door for under 21 Every 366 days, it returns. And each time, it claims more than the year before. This Halloween, BLKHRT resurfaces in Cleveland as ONSET transforms Grog Shop and B-Side into a two-floor descent through sound, art and controlled chaos. Downstairs, wander through a makeshift haunted mansion of surveillance rooms, looping films, strange artifacts and hidden pieces of the BLKHRT story. Leave your mark inside the Founder's Journal, catch yourself appearing across security monitors and explore rooms that feel increasingly less like they were meant to be found. Upstairs, the night erupts. Three DJs take control beneath a veil of projected visuals as live screen printing, falling Dark ONSET Money, black roses, balloons and unexpected moments blur the line between a Halloween party and a live production. Fear the FOMO.

Please note: This event is 18 and over. Any ticket holder unable to present valid identification indicating that they are at least 18 years of age will not be admitted to this event, and will not be eligible for a refund.
