Beach House looked overmatched against a crowd of nearly 9,000 people at their show at the Greek Theatre on Friday, April 8. But it’s easy to underestimate the Baltimore dream pop duo; they keep the stage sparse — just keyboards, guitars, drums, pedals and three musicians, crowded in a half circle.

The band, formed in 2004 by singer and keyboardist Victoria Legrand and guitarist and co-songwriter Alex Scally, are known for atmospheric, somber tracks, a formula saturated with reverberating guitar and swirling keyboard riffs. Their sound is tried and true; the duo have been releasing music for 16 years, stretching familiar signatures to their limits. Often suggested as music to cry to, Beach House makes music for quiet people with restless hearts.

很快就消除了对乐队是否能够为繁忙的户外露天剧场充满活力的任何疑问。With a blistering beam of white light illuminating the stage, peppered with the strobe beams that lit up Scally’s sequined letterman jacket, the pair — who are accompanied by touring drummer James Barone — opened up what would be a rather career-comprehensive setlist with the titular song off their eighth and latest record, “Once Twice Melody.” The song’s chorus repeats its title like a mantra, smothering the space it inhabits with each note. By the time it ended, the crowd was engulfed into Beach House’s sprawling melodic universe.

好像抢购了乐队的咒语，智能手机和摄像头是下一首歌的。从前几张笔记中只有一阵闻名，才意识到这是乐队2010年专辑“ Teen Dream”的“ Silver Soul”。粉丝们欢呼雀跃，凝视着他们的屏幕，暂时照亮了人群 - 乐队T恤中的人们的际交往组合，所有人都摇摆着并唱歌。

The next hour and a half explored cuts, both near and deep, from Beach House’s discography. While the visuals for them were minimal — mostly rhythmic lighting and shifting gradient backdrops — color slowly seeped into the set, wrapping around the three musicians’ silhouettes.

Legrand noted the night’s particular romance: playing a warm spring night to an audience atop a hill, under the stars. Small lights mimicked them behind the band, who led the moment with spiraling keys, as parts of the song “PPP,” off 2015’s “Depression Cherry,” fell into place.

“Someone once told me / In love, that you must / Place all you’re given / In infinite trust,” Legrand sang. The verse contrasts the narrator’s uncertainty, but at Friday’s show, it was fully meant. In the moment, those words were an amorous suspension of disbelief, an exchange between the artist and audience. Layers of sound lapped into the crowd; it was hard to tell whether it was Legrand’s roundabout vibrato or the echo of people singing along.

When Beach House returned on stage for the encore, the audience was greeted by Scally.

“This is the biggest show we’ve ever done,” he said.

To commemorate, they played “the first song they ever wrote” — “Saltwater,” from their 2006 self-titled debut album. It was clearly a rarity; the crowd roared, knowing they were about to witness something special. The song was significantly more distorted than anything the band played previously, lending it an air of naivete and nostalgia that had not been explored throughout the show, which largely explored the fitted gloss and sheen of their later albums.

As Legrand counted the band down to its final song, “Over and Over,” the voices of fans who sang along trailed away gradually, as if they were disembarking a carousel ride.

“The night that has no end,” she sang. “Over and over / Will be the last, my friend.”
