Halloween Block Party at Dirty Laundry and Madame Siam

Two neighboring Hollywood clubs open their doors for the same Halloween weekend. Dirty Laundry and Madame Siam, side by side on Hudson Avenue, are running what the promoter calls their most popular underground block party, and this year it spans both Friday night and Saturday night. If you are looking for things to do in Los Angeles on Halloween weekend that go past one crowded bar, this is a straightforward option: put on a costume, RSVP, and move between rooms.

When: Friday, October 30 and Saturday, October 31, 2026, from 10 PM Where: Dirty Laundry, 1725 N Hudson Ave, Los Angeles, CA 90028 (Madame Siam is next door) Price: Free with a Posh RSVP Presented by: Ledisko Nights

What to expect

The organizer promises three different rooms of DJs, so the music changes depending on which door you walk through. The listing does not name a lineup, and we are not going to guess at one. What it does say is that the party runs all weekend long, and that Saturday is Halloween night itself. The flyer leans into classic horror imagery, which fits the dress-up theme the promoter is asking for.

Both venues are small, dark and built for dancing rather than standing around. Expect the kind of packed, sweaty room that these Hudson Avenue clubs are known for, with costumes ranging from full prosthetics to a cheap mask and a good attitude. For anyone tracking EDM in Los Angeles this season, it is a lower-pressure alternative to the large festival-format Halloween shows.

Getting in

Per the flyer, entry is free on Posh until 11 PM with an RSVP ticket and a costume. Reserve the ticket ahead of time rather than counting on the door, since a free list on Halloween weekend tends to fill up. After the cutoff, door policy and pricing are up to the venue, so arrive early if you want to skip any cover. Bring a valid ID, as these are late-night club rooms and the listing runs past midnight.

Getting there

Hudson Avenue sits just off Hollywood Boulevard, in one of the densest nightlife stretches in the city. Street parking is scarce on a holiday weekend and nearby lots fill early, so rideshare or the Metro B Line to Hollywood and Highland, then a short walk, is the easier plan. Plan your ride home in advance too, because surge pricing hits hard after 2 AM.

If you are building out a list of LA events this weekend, you can browse more EDM events and other things happening in Hollywood before you lock in a plan. Friday and Saturday are separate nights, so you can pick one or do both.
