LSD was a supergroup consisting of British musician and rapper Labrinth, Australian singer-songwriter Sia and American music producer Diplo. The ensemble has released six singles (one of them a remix of their song "Genius"), all of which appear on their self-titled debut album, released on 12 April 2019.
On 11 March 2018, Diplo posted, to Instagram, a photo of a cassette tape with the letters "LSD" marked on it; in the caption, he tagged Sia and Labrinth. On 3 May 2018, LSD released their debut single, "Genius", along with an animated music video. The following day, Diplo revealed that LSD was formed when he was invited to write a song with Labrinth and Sia. Diplo said: "Originally, I wasn't in [LSD] and then our publisher had the idea to throw me in there; those two artists, together, are two of the craziest, most creative people I ever met in my life. I think they have the most severe attention deficit disorder together, their ideas are so crazy, so I helped put their ideas together, taking the job of their producer."
On 10 May, they debuted the song "Audio", as well as its music video. On 6 August, Sia teased the release of a new track titled "Thunderclouds", which was released three days later, on 9 August. LSD released the song "Mountains" on 1 November 2018. Talking to Rolling Stone in November 2018, Sia revealed that the group would release an album. The album, Labrinth, Sia & Diplo Present... LSD, was released on 12 April 2019 through Columbia Records.
In October 2020, Diplo stated via Twitter (now X) that LSD hoped to return for a new project.
Labrinth is featured on the track "Incredible", on Sia's album Reasonable Woman.
