Marshmello will headline a two-stage block party at The Midway SF on Friday, October 30, marking his first solo headline show in the Bay Area since 2018. The GRAMMY-nominated producer anchors a lineup that includes Armnhmr, CHYL, and Grabbitz, with additional artists expected to be announced closer to the date.

Venue and Format

The Midway SF has established itself as a hub for large-scale electronic events in the city, with its warehouse-style layout and multi-room configuration lending itself to the block party format. The two-stage setup will allow for simultaneous sets throughout the night, a structure that has become standard for standalone headline shows outside the festival circuit.

Support Lineup

Armnhmr, the bass duo known for melodic work in the mid-tempo and dubstep space, brings tracks like "Save Me" to the support slate. Grabbitz rounds out the announced lineup with his genre-blending approach that spans pop, rock, and electronic elements, making him a frequent collaborator in the bass music scene.

Production and Ticketing

Insomniac is producing the event, continuing its expansion of one-off club and warehouse shows beyond its festival calendar. An official afterparty is in the works, though details have not been released.

Presale registration is open now, with tickets going on sale July 27. General sale begins the following day.
