This is it. Weekend One of Austin City Limits Music Festival is almost over, but the party's just getting started.

Listen to our dispatch from ACL Fest Day 3 below:

Tonight, hip-hop queen Cardi B will take the Honda stage at 8 p.m. for what's sure to be a fiery headlining set. On the other end of Zilker Park, folk band Mumford & Sons will have a banjo blow-out on the American Express stage at the same time.

But it's the triple crown we've been waiting for that's got a lot of people excited. At 6 p.m., country star and former Austinite Kacey Musgraves plays the American Express stage, which will surely be followed by a mass migration to Lizzo, the chart-topping former Houstonite, on the Miller Lite stage. That's right next door to where Cardi B will play immediately after.

Before you can turn up, though, you'll have to endure the temperature turning up: We're expecting highs in the upper 90s. Fingers crossed that the forecast is right about the cold front that's supposed to come overnight.
