osno1 has been played on NTS shows including TT w/ DJ Pitch & Maya Vika, with ditch a body in the laundry first played on 12 July 2019.

Laura Les (born December 2, 1994) is an American singer, songwriter, producer and guitarist who makes up one half of the band 100 gecs along with Dylan Brady. Outside of 100 gecs she has her own solo music career, where she released music initially as osno1 before later using her own name.

Les grew up in a suburb of St. Louis, Missouri. As a teenager, she became interested in music while learning to play guitar. She later moved to Chicago in 2013, where she attented Columbia College. Laura studied acoustic engineering while she began releasing music online under the moniker osno1.

In 2016, Les released the EP "hello kitty skates to the fuckin CEMETARY", which she describes as "a bunch of songs about dead bodies." She subsequently released the 2017 EP "i just dont wanna name it anything with "beach" in the title".

In 2018, Les stopped using the osno1 moniker and released a third EP, "Big Summer Jams 2018" under her own name. The EP received positive reviews from music critics, praised as "debauched digital celebrations" by Vice and "a blender of fun” by Tiny Mix Tapes.

She also started working on the 100 gecs album "1000 gecs" with Dylan in her free time. They were collaborating over the internet during the creation of the album, but Laura later moved from Chicago to Los Angeles in 2020 in order to make working together easier after the album's success.

Les participated in a remix album of Katie Dey's album Mydata in early 2021. In March 2021, Les officially released her solo single "Haunted" following a positive reception from her fanbase after it was previously played during a virtual DJ set in 2020. The song was subsequently featured in season 2 of the HBO series Euphoria.

Les has cited being transgender as contributing to her exploration of different singing styles, including pitched-up "nightcore style" vocals, which she once used almost exclusively in her music due to her experiences with voice dysphoria. However, in a 2021 Pitchfork interview, she revealed she had begun taking vocal lessons and recording new 100 gecs music with unpitched vocals, saying, "As I've been exploring my voice more, I'm like, 'I can do this.'"
