Widely cited as one of the most influential figures in the early cloud rap era, Yung Lean rose to prominence in 2013 with his song "Ginseng Strip 2002", which went viral on YouTube. Later that same year, he released his debut mixtape, Unknown Death 2002, and the following year, he released his debut studio album, Unknown Memory.

He released the albums Nectar (2019), Blodhundar & Lullabies (2020) and Sugar World (2023) under the pseudonym Jonatan Leandoer96, a project which strays away from his hip-hop roots and goes for a blend of indie rock and neofolk.
