Marshmello Announces Bay Area Halloween Block Party

Marshmello is making a highly anticipated return to the Bay Area, choosing the spookiest weekend of the year to host a massive celebration. The GRAMMY-nominated producer will headline a two-stage Block Party at The Midway SF on Friday, October 30, marking his first headline performance in the region since 2018.

Joining the masked superstar on the bill are Armnhmr, CHYL, and Grabbitz. With more artists expected to be announced as the event nears, the production promises to be one of the season’s most significant electronic music gatherings. While details regarding an official afterparty remain under wraps, the primary event is already generating considerable buzz.

A Festival-Caliber Experience in the Heart of San Francisco

The Midway SF has solidified its reputation as a premier destination for large-scale electronic events. Its unique warehouse-style architecture and versatile multi-room layout provide the perfect backdrop for a block party format. By utilizing two distinct stages, the event allows for simultaneous sets, offering attendees a dynamic experience that mirrors the energy of a festival during the off-season.

For Marshmello, this performance signifies a return to a market that has long supported his meteoric rise. Since his breakout hits like ‘Alone’ and ‘Silence,’ he has cultivated one of the most recognizable brands in dance music. While he remains a staple at global festivals like EDC Las Vegas and Ultra, standalone headline dates of this magnitude have become increasingly rare, making this Halloween show a must-attend for Northern California fans.

Support and Production

The supporting lineup adds significant weight to the evening. The bass-leaning duo Armnhmr brings their signature melodic intensity, while CHYL and Grabbitz provide a diverse sonic palette. Grabbitz, in particular, continues to impress with his genre-blending approach, seamlessly weaving pop, rock, and electronic elements into his sets.

Produced by Insomniac, the event reflects the company’s ongoing strategy to bring festival-caliber production to intimate warehouse and club settings. By securing a high-profile artist like Marshmello for a Halloween date, they are effectively bridging the gap between massive festival experiences and local nightlife.

Tickets for the event go on sale on July 27. Fans are encouraged to register for the presale right here to secure their spot, with the general sale following the next day.
