Midjourney reports midnight music session at 300 Grant Ave spa site
David Holz posted a midnight improv session filmed inside the future Midjourney Spa and later identified the site as 300 Grant Ave near Union Square. The clip turns this week's spa talk into a real, publicly locatable creative space rather than a distant plan.

TL;DR
- Midjourney turned a vague future-spa idea into a specific place when DavidSHolz's midnight post showed a filmed music session inside the unfinished space, and DavidSHolz's address reply placed it at 300 Grant Ave near Union Square.
- The clip was not a polished launch asset. In DavidSHolz's follow-up, Holz said he posts things like this often but rarely has a chance to share a public video.
- DavidSHolz's scanner reply and DavidSHolz's public-access timeline say the San Francisco site is meant to house Midjourney scanners, with public access targeted for the end of 2027 and research trials before then.
- Holz framed the place as more than a clinic-style install: DavidSHolz's 24/7 reply said he wants a late-night hangout, while DavidSHolz's vibe-tools reply called Midjourney's products "the best vibe ai tools."
You can watch the midnight improv session, jump to the address confirmation, and trace the bigger plan through the scanner deployment reply and the public-access timeline. There is even a small aesthetic tell in Holz's acoustics comment, where he says he brought friends because he wondered how the room sounded.
300 Grant Ave
The most concrete update in this week's spa chatter is the address. In DavidSHolz's address reply, Holz said the site is "300 Grant Ave near Union square and the apple store."
That turns the spa from a floating concept into a publicly locatable downtown San Francisco space. DavidSHolz's first-one-in-SF reply also points to a linked post confirming the first location is in San Francisco.
Midnight blessing
The first look at the interior came from DavidSHolz's midnight post, which invited followers to "come hang" for ten minutes past midnight while he and friends improvised "a musical blessing on the empty space" of the future Midjourney Spa.

In DavidSHolz's acoustics reply, Holz said he wondered whether the acoustics were good and brought friends to check. In DavidSHolz's filming reply, he added that he was filming and making the song theme request himself.
Late-night clubhouse
Several replies sketch the mood Holz wants around the space. DavidSHolz's 24/7 reply said it will be "really fun" to try keeping it open 24/7 because he wants more cool places to hang out late at night.
That fits with the way he talks about Midjourney's broader product identity. In DavidSHolz's vibe-tools reply, Holz wrote, "we make the best vibe ai tools," and in DavidSHolz's artisanal-AI joke he called Midjourney's AI "the most artisnal AI too :3."
Scanner timeline
The music clip matters because it sits on top of a more specific hardware plan. In DavidSHolz's spa-build reply, Holz said Midjourney is building a spa with scanners in it, plans to build more around the world, and is still figuring out other form factors.
The current timeline in the thread is:
- DavidSHolz's scanner deployment reply says the scanners are being deployed in a Midjourney Spa in San Francisco, with availability hoped for by the end of 2027.
- DavidSHolz's public-access timeline says research trials will happen before the opening, and that the San Francisco spa is the main way the public will use it at first.
- DavidSHolz's second-city reply says San Francisco is the starting point, while Los Angeles is one possible next city under discussion.
That leaves the midnight session as both a vibe post and a location proof. The room already exists, even if the public-facing scanner experience is still on a 2027 clock.
