Originally the post-rock project of composer/keyboardist/vocalist Ryan Lott, Son Lux grew over the course of the 2010s to include guitarist/composer Rafiq Bhatia and experimental drummer Ian Chang. Combining live instruments with computer-manipulated acoustic performances, samples, and Lott's strained vocal delivery, Son Lux's bold, dystopic sound often correlates with anxious lyrics about a fearful future. These seeds were planted on the off-kilter debut album At War with Walls Mazes in 2008, before 2013's more-striking Lanterns featured songs that were later covered by Lorde and sampled by Fall Out Boy. The first Lott-Bhatia-Chang collaboration, 2015's Bones, marked the project's debut in the Top Ten of Billboard's dance/electronic albums chart. Son Lux's sixth album overall was a three-part concept work titled Tomorrows, the third installment of which arrived in 2021 and was followed with their soundtrack to the acclaimed indie film Everything Everywhere All at Once (2022).

The youngest of three children, Lott spent much of his childhood moving from place to place. Born in Denver, Colorado in 1979, he lived in California and Connecticut before landing in Atlanta for high school. He began studying classical piano at age six; he later learned guitar, and in Georgia he picked up the drums and delved into pop and jazz piano as well. While studying composition and piano at Indiana University, Lott first explored writing for dance choreography. He continued in that vein not only after graduation when he was living in Cleveland -- where, as the recipient of an arts grant, he was able to spend time working on his own music and its interaction with other media -- but also after he moved to New York City in 2007 for a job as a composer at an ad agency. There, he continued his collaborations with the Gina Gibney Dance Company, an all-female modern dance group.

During this same time, Lott decided to pursue his solo work, using tiny samples and his own voice to make ethereal, nocturnal music that drew from experimental rock, hip-hop rhythms, and electronica arrangements under the guise of Son Lux. He won a songwriting competition that gave him the opportunity to perform (for the first time under his new moniker) at the Festival of Faith & Music in Grand Rapids, Michigan, opening for artists including Emmylou Harris and Sufjan Stevens, and soon he was playing in New York City and remixing songs by artists like Beirut and Castanets.

Signed to Anticon, Son Lux released his debut album, At War with Walls Mazes, in March 2008. For his second album, Lott had to completely upend his normally slow and careful creative process after being invited to participate in the 2011 RPM Challenge, in which musicians attempt to completely write and record an album in the month of February. This was a major change for him, as At War with Walls Mazes took four years to create, but Lott stepped up to the challenge, releasing We Are Rising in 2011.

Two years later, Lott signed with Joyful Noise and returned with the third Son Lux studio album, Lanterns. Here he further refined his techniques of digitally manipulating his often acoustic-instrument recordings for an unearthly, quasi-electronic sound. In 2014, Lott appeared on the album Sisyphus, a collaboration with Sufjan Stevens and Serengeti, and he released the Son Lux EP Alternate Worlds, which re-envisioned tracks from Lanterns. It featured contributions from New Zealand pop star Lorde, who had covered the track "Easy" at live shows. Meanwhile, Lanterns' "Lost It to Trying" was heavily sampled on Fall Out Boy's song "Fourth of July," which appeared on their chart-topping American Beauty/American Psycho album from early 2015.

After touring on and off for a few years, often solo, Lott assembled a regular touring band to promote Lanterns and liked their chemistry so much that all three musicians co-wrote and recorded the fourth Son Lux long-player. In June 2015, the brash, dystopian-feeling Bones was released on Glassnote Records by the trio of Lott, guitarist Rafiq Bhatia, and drummer Ian Chang. Written during the week of the 2016 U.S. presidential election, the trio returned in May 2017 with Remedy, an EP that featured a crowdsourced choir of over 300 voices.

Son Lux then signed with City Slang, which released 2018's Brighter Wounds. A more personal album affected by both loss and the birth of Lott's first child, it featured guests including the chamber sextet yMusic and trumpeter Dave Douglas. Released the same year, the companion EP Yesterday's Wake reimagined some of the record's musical themes. Another peripheral release, 2019's Labor, compiled instrumental and alternate versions of tracks from Brighter Wounds. Looking back to sessions prior to that album, 2019's Remnants (Joyful Noise) consisted of rarities, previously unreleased songs, and outtakes recorded between 2008 and 2017. Continuing to reach into the archives, Son Lux issued the EP Reincarnates in May 2020. It collected unreleased material including a live version of "Alternative World" and the original song "DBML" featuring Chris Thile. Son Lux also reimagined two earlier songs with singer and interview subject Bonnie Piesse for the HBO documentary series The Vow, one of which, "Dream State (Brighter Night)," served as the theme.

In August 2020, Son Lux returned to City Slang with the first installment of a trilogy of original albums called Tomorrows. Influenced by events spanning climate change, growing inequality, the COVID-19 pandemic, and widespread political protests, Tomorrows I offered songs and instrumentals conceived around the themes of "imbalance, disruption, collision, redefinition." Its guests included a string quartet and vocalist Kadhja Bonet. The leaner, more introspective Tomorrows II followed that December, with the striking Tomorrows III arriving in April 2021. It included appearances by Bonet and singers Holland Andrews and Kiah Victoria. Tomorrows Reworks followed later in the year, and that December brought the single "Gone," a collaboration with Kimbra for the Netflix sci-fi animated series Eden.

Son Lux's nearly two-hour soundtrack for the action-sci-fi-comedy-drama Everything Everywhere All at Once was released alongside the film by A24 in March of 2022. In addition to its lengthy score, which essentially provided otherworldly sound effects as part of its musical design, it included songs with Randy Newman, Moses Sumney, and Mitski and David Byrne (single "This Is a Life"), among other guests. ~ Marcy Donelson & Marisa Brown, Rovi
