Weekend two of Austin City Limits Music Festival kicked off on Friday (Oct. 11) in Zilker Park, and it was definitely a lineup full of gems for what was surely a crowd dominated by millennials.

With headliner blink-182 along with a number of early aughts favorites, a throwback to much simpler times, coming just weeks ahead of a contentious U.S. election. For last weekend and this one, however, ACL offered a cozy bubble of familiarity. A very, very hot bubble, mind you, but a bubble nonetheless.

Early in the day, rising country singer Dasha delighted fans at the American Express stage. It comes as Dasha continues to draw comparisons to one of the biggest pop stars on the planet, Taylor Swift. Having welcomed the association, the singer is now carving out her own space in music, and she offered up an exciting show on the main stage.

Next up was Bre Kennedy on the BMI stage, delivering such an enthralling performance with a group of fans who seemed to know much of her music. For those who weren't already lured in by her lush, magnetic vocals, she capped her set with a cover of John Mayer's 2003 single "Daughters." It was perhaps the first glimpse of the throwback gems around the park over the course of the day. Kennedy closed out her performance with her own standout track "Hello."

Over on the IHG Hotels & Resorts stage, Mickey Guyton gave one of the most delightful performances of the day. The singer, who is originally from Arlington, Texas, noted how brutally hot it was in Austin before launching into her song "Better Than You Left Me." In her taping of ACL Live last weekend, she covered Beyoncé's 2008 single "If I Were a Boy," both a tribute to her fellow Texan and another nice throwback.

Norah Jones was such a welcome bright light on the Honda stage, with a throng of people watching as the singer took fans back to a different era. It was beautiful and also sort of shocking to this millennial, as her breakout moment was a whopping 22 years ago. How is that even possible!?

Of course, Jones had the entire crowd in the palm of her hand by the end of her set as she gave the fans the live rendition of one of her biggest songs, "Don't Know Why." She was all smiles as the audience began singing aloud with her. 

As another reminder of how quickly time passes, St. Lucia took the IHG stage later in the afternoon, keeping the crowd happy with a string of glowing dance-pop cuts. Earlier this past week, the band noted on social media that it's been 11 years since their debut album When the Night was released. Sticking with the trend of crowd favorites, the band closed out their phenomenal set with their breakout single "Elevate."

Next, it was on to Royel Otis on the Miller Lite stage, where the Sydney duo signaled they could easily be part of a next wave of alt-rock/pop standouts, opening with their shimmering single "I Wanna Dance with You," before leading into their popular cover of The Cranberries hit "Linger" and closing out with their own fan favorite "Oysters in My Pocket." On a day full of reminders of the past, Royel Otis was a glimpse of the future.

The nostalgia continued back on the Honda stage, where Foster the People delivered a golden hour set leading into some of the biggest songs, including "Houdini" and then, of course, "Pumped Up Kicks," which was was preceded by an intro from frontman Mark Foster, who encouraged the audience to support local and rising artists so that the next generation of new acts could find success and allow their voices to be heard. It was clear the majority of the crowd had been hanging out waiting for "Pumped Up Kicks," as there were more than a few times Foster backed away from the mic and let the fans take the lead. It was a true singalong and one of the best moments of the day.

There was no better representation of nostalgia than when headliner Chris Stapleton opened his own set not with a big, thundering entrance as he does for most of his shows. Rather, he was seated next to a Texas legend, the one and only Willie Nelson, who joined him for an intimate acoustic performance including "Whiskey River," a song they previously performed together last year for Nelson's Rock and Roll Hall of Fame induction.

"I cannot exaggerate how much I loved that moment. I hope you enjoyed it too," Stapleton said as Nelson exited the stage and Stapleton launched into his official setlist, opening with his incredible single "White Horse."
