Mila de la Garza powers “No Obligation” with a furious thump that feels like a punk rock drumming clinic. Around the pounding, guitarists Bela Salazar and Lucia de la Garza and bassist Eloise Wong fill in heavy riffs and power chords. Overtop it all, Wong shouts, “I don’t owe you/You don’t own me/You don’t owe them/They don’t own you.”

“For me on ‘No Obligation,’ I don’t think I was really experimenting with different sounds, but more figuring out how to sound more like myself,” Wong told the Boston Herald about writing the title track to the Linda Lindas’ 2024 album.

The Linda Lindas have come to specialize in punk rock, heavy riffs, and defiant shouts. And come to specialize in a short span of time. The members — aged 14 to 20 — have carried the viral stardom of the 2021 song “Racist, Sexist Boy” into the strong, smart second LP “No Obligation.”

“(2022 album) ‘Growing Up’ was us throwing together some of the first songs we’d ever written,” Wong said ahead of the Linda Lindas’ April 23 show at the Paradise. ‘“No Obligation’ was us finding how to make the kinds of music we like.”

Turns out the music the Lindas like is hardcore, pop punk, indie pop, noise rock and Latin-influenced experiments (listen to “Yo Me Estreso,” which features Weird Al on the accordion). The lyrical themes that go with tunes range from big ideas about culture and politics to personal stuff like life stress and pets.

“We just write about our lives and whatever feels important to us in the moment,” Salazar said. “Sometimes that’s something political, sometimes it’s something personal, or even just about my cats. We’re not really trying to strike a balance or overthink it, it just kind of reflects where we’re at now.”

“I’ve always been a very introspective writer, which makes a lot of my songs a lot more personal, but it’s always in the context of something bigger,” Lucia de la Garza said. “I think our balance also comes from each other, and helping each other stay grounded.”

Staying grounded is key when you spend half your life writing, recording, and touring — last summer the Linda Lindas played stadiums and arenas with Green Day and the Smashing Pumpkins; in the fall, “No Obligation” racked up millions of streams and four star reviews. The other half of life is filled with regular stuff like school.

“School actually is pretty grounding when we’re at home; it helps keep some sense of ‘normalcy,’ ” Mila de la Garza, the 14-year-old drummer, said. “In my free time I like to read. I recently finished ‘The Secret History’ by Donna Tartt and am in the process of reading some Rainbow Rowell books right now.”

Teen life is tough enough to navigate without being in one of the great new bands of today. Of course, adult life can be no picnic. In the mess of the modern world, the Linda Lindas find time for rage, joy, and normalcy.

“It’s so easy to give up amidst daily depressing news of censorship, deportation, war, and how our government is stripped down to only benefit the elite few and screw over the rest,” Wong said. “All these issues feel so big and too much to handle, but we can start with caring, talking, and doing what we can among our friends, in our smaller communities, and maybe even in silly little rock shows we play.”
