Jonatan Aron Leandoer Håstad (born 18 July 1996), better known by his stage name Yung Lean, is a Swedish rapper and record producer. Yung Lean released his debut mixtape in 2013 (entitled Unknown Death 2002) and multiple singles to YouTube under his label Sad Boys Entertainment, including “Ginseng Strip 2002”, “Kyoto”, and “Yoshi City”.Lean released his debut album Unknown Memory during the late summer of 2014 following a two-month long American tour.
Håstad met Yung Sherman and Yung Gud in a local Stockholm park and they struck up a friendship, discovering they enjoyed much of the same music. Together, they formed what was known as Hasch Boys, which consisted of Lean, Sherman and Gud along with other Stockholm individuals who later became a part of Gravity Boys Shield Gang.
When all of the other members started losing interest in “Hasch Boys”, it left Lean, Sherman and Gud coming to realization that they were the only active members. As a result, they then formed a trio of what was then known as “Sad Boys”. By 2012, Yung Gud and Yung Sherman began producing and mixing music while Yung Lean would write lyrics and record vocals and would upload an array of these songs to his SoundCloud profile.
