Los Angeles County is now under a new mask mandate (again) — which went into effect at midnight — but before the clock struck 12 … Angelenos got in their last bit of maskless fun — especially at SoFi Stadium … with Kaskade behind the wheel.

The venue was jam-packed with people Saturday during the EDM DJ’s headlining set … which got underway not long before people would be forced to cover their mouths and noses once more … due to a new surge in coronavirus cases, of course.

Check out the video … concert-goers were huddled close together, and there didn’t seem to be very many masks (if any) among the crowd. Seems they were milking the opportunity down to the last hour, because as of 12:00 AM PT — the mandate went into effect.

It’s unclear just how many people showed up for Kaskade and co. … but considering the place has a capacity of 70,000 seated (and even more standing), we’d say it was probably close to that, based on how crowded it looked from a quick glimpse.

If COVID numbers are, in fact, surging again like they say … then this definitely doesn’t seem like the best way to spend one’s time right before another masking rule gets ushered in.

Still, these people made their decisions … and didn’t seem to regret it. Stay safe, y’all.
