Yung Lean

Yung Lean in Sweden

In 2012, Håstad met Yung Sherman and Gud in a local Stockholm park and they struck up a friendship, discovering they enjoyed much of the same music, going on to form the collective Hasch Boys.[12] Another group of Stockholm artists who would later form the group Drain Gang were also members.

When many of the other members of Hasch Boys began to lose interest in the group, Håstad, Sherman and Gud broke off and formed the group "Sad Boys" as a trio.[13] By 2012, Yung Gud and Yung Sherman were producing and mixing music while Håstad had begun writing lyrics and recording vocals in a makeshift studio in his basement. They shared the music they made on the platforms SoundCloud and Tumblr,[14][15][16] where Lean began to generate a large following.[17][18] Sad Boys performed their first show in Gothenburg, Sweden on 5 May 2013.

Yung Lean became widely known when the music video for his track "Ginseng Strip 2002" went viral.[19][20][21][22] Later in 2013, he put out his first official releases: Marble Phone, a single featuring Kreayshawn, Unknown Death 2002 and an EP titled Lavender which includes the track "Ginseng Strip 2002" along with other songs that were cut from Unknown Death 2002. Consequence of Sound placed "Ginseng Strip 2002" at number 44 on their "Top 50 Songs of 2013",[23] while Vibe included Unknown Death 2002 in their list, "The 10 Most Overlooked Debut Rap Mixtapes of 2013", describing it as "a natural progression from the freely associative, often nonsensical rhymes of Lil' B with a keener sense of melody".[24]

In 2013, Yung Lean and Sad Boys toured throughout Europe. Later that same year, Acclaim Magazine had Yung Lean as their guest for a Q&A "smalltalk" segment, where they asked him about a wide variety of miscellaneous things, including his favourite hangover cure and his desktop wallpaper.[25]
