A native of Northern California who spent most of his childhood in South Africa, Leng trained as a classical pianist for over a decade before experimenting with electronic textures. He was based in southern California by the time he started sharing his productions, beginning with May 2013's "Crawled out of the Sea." Two months later, he found an audience numbering in the tens of thousands with the follow-up, "Crawled out of the Sea." He continued to release periodic stand-alone tracks before issuing his first EP, Tunnels and Planes, in early 2015. In addition to its well-received title track, it included the viral hit "Inside Your Mind" featuring Carmody.
In mid-2016, B3SCI Records released Leng's self-produced Drivers EP, which more prominently featured his warm, conversational singing. Later that year, he was featured on the StéLouse track "Been So Long," which he also co-wrote. Leng returned in late 2018 with a lusher, giddy indie pop sound on the songs "Ticking" and "Lemons." ~ Marcy Donelson
