Whethan Takes Over Sound Bar for an Official Lolla Aftershow

Lollapalooza weekend rolls into the late-night hours on August 1 when Whethan headlines the official 21+ aftershow at Sound Bar in Chicago, kicking off at 10:00 PM CT. If you spent the day on the festival grounds, this is where the party keeps going — but the sky isn’t done with Chicago yet.

Weather: Storms Are the Story Tonight

The National Weather Service is forecasting showers and thununderstorms for the overnight period, with a 96% chance of precipitation and a low around 68°F. Wind is expected out of the east southeast around 20 mph, and NWS notes new rainfall amounts between a half and three-quarters of an inch are possible. Skies stay cloudy through the night.

Translation: this isn’t a “maybe bring a jacket” situation — rain is very likely to factor into your night out. With 68°F temps and steady wind on top of the rain, it’ll feel cooler than a typical August evening, especially if you’re waiting in line outside before doors.

What to Wear and Bring

Skip anything you can’t afford to get soaked. A packable rain jacket is the easiest way to stay dry between the taxi/rideshare drop-off and the door without overheating once you’re inside dancing. If you’d rather keep your hands free of a jacket altogether, a compact travel umbrella is worth tossing in a bag for the walk over — just know Sound Bar is an indoor venue, so you won’t need it once you’re through the door.

With 20 mph wind in the mix, layer smart: something breathable underneath your rain layer so you’re not sweating on the dance floor an hour after arriving damp from outside.

Aftershow Essentials

Late-night sets like this one run long, and between navigating Lolla all day and then an aftershow, your phone battery has probably already taken a hit documenting the festival. A portable phone charger 20000mah means you’re not stuck searching for an outlet — or missing the moment you finally catch Whethan’s set on video — because your battery died mid-show.

Practical Tips

Sound Bar is a 21+ venue, so have your ID ready. Given the rain and wind in the forecast, budget extra time for your rideshare or walk over — wet Chicago streets after a full day of Lollapalooza foot traffic can mean slower-than-usual pickups. Arrive a little early to avoid getting caught in a downpour while you wait outside.

Bottom Line

With a 96% chance of rain, a 68°F low, and 20 mph wind working against you, the move tonight is simple: throw a packable rain jacket on before you leave, keep a compact travel umbrella and a portable phone charger 20000mah in your bag, and let the storms outside stay outside while Whethan handles the rest.
