Overview

Think you can handle the things that go bump in the night? Insomniac's BOO! Halloween massive was unearthed in 2014 in New York, and has brought the hair-raising sounds of dubstep, house, trap and more to various locations around the US including SoCal, San Francisco, Arizona, Orlando and Dallas. The inaugural Seattle edition in 2021 expanded BOO! to a full-scale, 3-stage festival for maximum Halloween scares. Look out, it may haunt a city near you in the future...
