This Halloween, Invisible City invites you to participate in a night of dark enchantment.  Featuring a private performance by all 57 Members of Itchy-O, the legendary experimental music collective, and a lineup of Denver’s best DJs. Costumes are highly encouraged. Let’s create a ritual of our own making.

Following Itchy-O, the party continues with NEVERMORE, featuring three DJ sets by JÅZ, SWEVEN, and THUNDERTHIEF. Descend into the sonic abyss, amidst the shadows, uncover the profound wonder, and from its depths, emerge to a future worthwhile.

Food and drink will be available until closing.



Itchy-O is an avant-garde music performance group from Denver, Colorado. The group is made up of 57 members, including 23 professional musicians.

Their instruments include percussion, electronics, and traditional instruments like taiko drums. They also use pyrotechnics and custom-built waveform equipment.

Itchy-O’s performances are designed to create spiritual experiences for the audience. They want to disorient the audience’s sense of place, time, order, reason, and identity. Some say the performers’ hypnotic percussion sounds and the way they move through the crowd make the audience feel like they’re in a trance.

Jaz McDonald is a multi-talented musician, producer, and DJ whose diverse musical upbringing has shaped his unique sound. Spanning the realms of progressive rock, electronic, and cinematic music, Jaz has crafted an immersive sonic experience that captures his undeniable passion

Sweven is a Denver-based electronic music producer and DJ. Combining elements from a multitude of music genres, including future bass, trap, dubstep, house, and more, his experimental sound design will take you on a new and unique sound journey with every track.

The first to coin and cultivate the ‘alt-house’ subgenre, Thunderthief melds sultry synths, emotive guitar licks and bountiful bass amidst melodic house undertones to create rich, tapestries of sound.

Deemed the ‘Best DJ-producer in Class’ by Vertex Music Festival, the producer has since garnered critical-acclaim across the live-events sphere for his double deck bass-guitar live performances and transcendent DJ sets.
