Mersiv brings "Pretty Dark Loud" bass to Brooklyn Steel in March

The Denver bass producer has booked Saturday, March 6, 2027 at the 1,800-capacity Williamsburg room, and tickets are live through AXS.

Some bass music is built for festival fields. Mersiv makes the kind that needs a ceiling and walls to bounce off, and on Saturday, March 6, 2027, it will get one in Brooklyn.

Mersiv announced the date at Brooklyn Steel on Oct. 28. Doors are at 7 p.m. and the show starts at 8 p.m. The room holds 1,800, and tickets are on sale now through AXS. Four months out is early, but an announcement-week ticket for a room this size is usually the easy one to get. Waiting until the week of the show is the hard way.

For Manhattan readers who haven't caught up: Mersiv is the stage name of Anderson Benoit Gallegos, a Denver-based DJ and producer. 303 Magazine's profile traces the story from a mother's CD collection to throwing parties in barns to build a community of bass fans. It continues to a move to Colorado with very little money, where Mersiv soon met manager Tank Reed. Insomniac dates the project's start to 2015. Since then, Mersiv has been refining what Insomniac and the artist call a "Pretty Dark Loud" style of bass music.

That phrase is also the title of Mersiv's sophomore album. This Song Is Sick described the 20-track record as a soul-shaking trip through the genre. It's the best map for what a Brooklyn Steel set should feel like: weighty, slow-burning low end with melodic light cutting through it, rather than a nonstop drop parade. Dubstep FBI puts Mersiv at the front of the "deep dub" and experimental bass lane.

Mersiv's sound needs a ceiling and walls to bounce off.

The rise has been steady rather than sudden. Pollstar named Mersiv a Hotstar in 2023 as Colorado's rising bass music star. The trade noted that after a first-year splash at Electric Forest, bigger names in the scene came calling. By 2019, Mersiv was sharing lineups with Zeds Dead and Liquid Stranger. This fall brought the clearest marker yet: a headline night at Red Rocks on Oct. 23, 2026, announced with two Mersiv sets on the bill.

The Brooklyn date also lands in a busy stretch. A Shotgun listing bills a February 2027 Gainesville, Florida date as part of a Mersiv Nostalgia Tour, so the artist will be on the road in the weeks before New York.

The room matters here. Brooklyn Steel is a big, open box with 1,800 tickets to sell, enough for a headline production but small enough that the low end hits your chest instead of drifting away over a lawn. A producer who got to Red Rocks by building a community from barn parties up is a good fit for a room that size. It's a headline night for a crowd that came on purpose.

The bill so far is Mersiv alone. Watch the JamBase listing and the AXS page for support acts as the date gets closer.

If you've only heard this music through earbuds on the L train, March is the chance to hear what it's meant to do in a room. Buy the ticket now, and bring earplugs anyway.
