Lauv

When: Sunday, 4:40 p.m., Downtown Stage.

HQ: LA.

Sound: Lauv (aka Ari Leff) is a modern sonic chameleon who shape-shifts between sleek R&B—check out his falsetto on “Paris in the Rain”—and Ed Sheeran-caliber acoustic-pop.

Spin: The snappy electro remix of “I Like Me Better,” which illustrates that romantic bliss can be a self-esteem boost.

The Presets

When: Friday, 8:40 p.m., Fremont Stage.

HQ: Australia.

Sound: For well over a decade, the vocals/drums/keyboard duo has conspired to create riotous dance music that nods to booming EDM, pulsating electro-pop and thrashing synth-rock.

Spin: “Martini,” a sweltering, techno-diffracted bit of ’80s-inspired house that’s both unabashedly retro and boldly futuristic.

Welshly Arms

When: Saturday, 3 p.m., Downtown Stage.

HQ: Cleveland.

Sound: Although frontman Sam Getz’s gritty vocals and electric guitar conjures The Black Keys’ garage-rock days, scrappy indie act Welshly Arms distinguishes itself with soul- and gospel-pop flourishes.

Spin: “Legendary,” an empowering, blues-drenched tune adorned with insistent piano and cascading harmonies.

lovelytheband

When: Sunday, 3:30 p.m., Downtown Stage.

HQ: LA.

Sound: This upstart power trio—fronted by Mitchy Collins, notable for his recent tenure in Oh Honey—favors contemporary modern rock with slippery electronic flourishes and a sleek pop sheen.

Spin: “Broken” topped Billboard’s Alternative Songs chart for weeks earlier this year on the strength of a relatable sentiment: The narrator bonds with a significant other over loneliness and emotional baggage.

Hind

When: Friday, 5:25 p.m., Huntridge Stage.

HQ: Spain.

Sound: ’90s indie throwbacks with a distorted garage-rock center.

Spin: “Finally Floating,” on which a snaky, fuzzy guitar darts between the quartet’s overlapping vocals to create a disorienting vibe.

Superorganism

When: Sunday, 4:55 p.m., Bacardi Stage.

HQ: London.

Sound: A genre-bending indie-pop troupe interested in the power of collective artistic creativity.

Spin: “Everybody Wants to Be Famous,” a dizzying pop pastiche stitching together hip-hop, new wave, electro-rock—and all points in between.

SOFI TUKKER

When: Sunday, 7:30 p.m., Fremont Stage.

HQ: New York City.

Sound: This eclectic duo specializes in electro anthems incorporating everything from Brazilian poetry to sizzling house beats.

Spin: “Best Friend,” featuring Nervo, The Knocks and Alisa Ueno, is an exuberant dancefloor contortion celebrating the joys of finding your soulmate.

Mt. Joy

When: Sunday, 6:50 p.m., Huntridge Stage.

HQ: LA via Philadelphia.

Sound: Indie-folk distinguished by atmospheric keyboards and a soulful edge that elevates the group above the acoustic-rock fray.

Spin: The beatific “Silver Lining,” which compresses everything great about the band into three minutes: emotion-burnished vocals, an earworm hook, lush arrangements and shivering guitars.

Get down at the forest house art car

First Burning Man, then Electric Daisy Carnival. Repurposed, DJ-commandeering vehicles have become a bona fide musical complement at our larger festivals—and count Life Is Beautiful in there, too. For the second year in a row, the Forest House Art Car will be stationed off Seventh Street across from the El Cortez, boasting tens of thousands of LEDs and a daily DJ lineup—with Cosmic LA curating Friday, Collective Zoo on Saturday duty and We the Beat staffing the booth on Sunday. Most of the talent has been announced, notably Australian DJ Wax Motif, LA’s The Klassiks, the mostly local lineup on Sunday and … a surprise guest performer each night. Any LIB-goers wanting to get their dance on, just look for the glowing trees. –Mike Prevatt
