German rapper Kay One signed with Bushido's Ersguterjunge label in 2007. Building up his popularity with guest appearances, compilation cuts, and free download tracks, Kay won a Juice Award in the Newcomer category in 2009 and then released his first solo record, Kenneth Allein zu Haus, in May 2010. The album, which featured guest appearances by Bushido, Fler, Frauenarzt, and others, reached number seven on the German album charts. The same year, he teamed up with Bushido and Fler to release the album Berlins Most Wanted, which charted at number two. Kay One's second solo album, Prince of Belvedair (number four in Germany and Austria), was released in early 2012, shortly before the rapper announced his departure from the Ersguterjunge imprint. ~ Christian Genzel
