The teen singer-songwriter is celebrating the one-year anniversary of her award-winning debut album, “Sour” with two sold-out shows in Los Angeles this week.

Olivia Rodrigo teared up as she told the sold-out crowd at the Greek Theatre in Los Angeles on Tuesday night that playing the venue was one of her lifelong dreams.

Growing up in Temecula, Rodrigo shared that her parents would drive her to L.A. for acting classes and they’d cruise by the Griffith Observatory, which overlooks the iconic outdoor concert venue. Her voice cracked as she said she told her parents back then that she’d perform at the venue someday.

“Feels good to be home,” the 19-year-old singer-songwriter said through emotion and deep breaths, having just opened her first of two nights at The Greek with the fiery, pop punk-infused “Brutal” and a rocked-out version of “Jealousy, Jealousy.”

Rodrigo didn’t just play the Greek Theatre – she owned it. Fans lined up well before doors opened and squeezed inside the venue to snag as much purple and black merchandise as possible. They took selfies with a variety of backdrops and made sure to put the finishing touches on their glittery homemade signs that expressed their devotion and celebrated the one-year anniversary of Rodrigo’s debut and multi Grammy Award-winning album, “Sour,” which brought them all together.

None of that seemed lost on Rodrigo as she stood at the end of the stage in her glittery pink corset top and matching plaid pink skirt. She let the special moments sink in and there were several throughout the evening. As she jumped on the piano and belted out the lyrics to her wildly popular debut single “Drivers License,” she poured her heart out and the audience was right there with her, passionately — and very, very loudly — singing through their emotions.

The fans were mostly female and ranged in age from young teenagers to women in their 30s and 40s. For the more experienced women in the crowd, Rodrigo’s lyrics, songs and performance is reminiscent of the women who rocked the ’90s like Gwen Stefani, Fiona Apple and Alanis Morissette. Before she took the stage, two generations were dancing and singing along to Apple’s 1996 hit “Criminal” and Hole’s 1994 jam “Doll Parts” as they blasted out of the speakers.

Rodrigo cites all of those women as major influences on her career and songwriting; she’s been covering Veruca Salt’s “Seether” and No Doubt’s “Just a Girl” on the road, but she saved something special for the hometown crowd. She brought out Morissette to duet on what she said is “the greatest break-up song ever written,” and the pair, along with Rodrigo’s badass all-female band, launched into Morissette’s “You Oughta Know.”

“This is probably the favorite night of my whole life, thank you guys for coming,” Rodrigo said, giddy after having just ripped through one of her favorite songs with one of her idols whom she referred to as “an angel.”

Though it was an evening of celebration, Rodrigo, just barely out of high school herself, did address the school shooting in Uvalde, Texas that took place earlier on Tuesday, which left at least 19 elementary school-aged children and two teachers dead.

“We need stricter gun control,” she said closing out the first act of the evening and sharing that kids should “never have to worry about their safety and lives” in places of education and learning. Her tour also took a hard stance on COVID-19 vaccinations. Last year, Rodrigo teamed up with Dr. Anthony Fauci and President Joe Biden for a campaign to urge young people to get vaccinated. Her Sour Tour is one of the traveling productions that continues to require proof of vaccination for all fans ages 12 and older.

Rodrigo knows she has the ear of young fans and seems to take that responsibility seriously, speaking candidly about current affairs as well as mental health and dealing with typical teenage stuff — petty drama, jealousy, heartbreak, pressures of growing up and comparing yourself to others. Her message is both encouraging and empowering, yet she still appears vulnerable as she admits to at times feeling “not good enough.” She wrote two songs, “Enough for You” and “1 Step Forward, 3 Steps Back,” about not feeling like she was enough and “now I get to play them at my sold-out show at the Greek Theatre,” she quipped before performing them back to back.

After soaring through the ballad “Traitor” and having nearly the entire venue shouting the chorus to “Déjà Vu,” the evening came to a rowdy close with her hit “Good 4 U,” which had fans dancing in the aisles all the way through the massive confetti finish.

Rodrigo’s opening act, British singer-songwriter Holly Humberstone, who just performed both weekends of the Coachella Valley Music & Arts Festival in Indio in April, also delivered an impressive set. She was solo on stage, surrounded by instruments and she used looping to thicken her sound as she strapped on a guitar and played songs like “Vanilla,” “The Walls Are Way Too Thin” and “Scarlett.”

Though she admitted to being “an awkward person,” her in-between songs banter came off as genuine and she shared quick personal stories about most of the material. Support and opening acts don’t always receive the warmest welcomes in Southern California; however, Humberstone managed to captivate this crowd as those that seemed less familiar with her work soon joined in on the fun, raising up their cell phone flashlights and swaying along. These moments seemed to catch Humberstone off guard and as she finished “Please Don’t Leave Just Yet,” she took an audible breath, scanned the crowd and just said, “Sweet.”
