He first came into contact with hip-hop and its elements at the age of ten.
In the following years, he continued to increase his level of awareness. After a broken contractual relationship, he finally joined the legendary Stuttgart rap combo Chaplin Records in April 2007. Alongside Duap MC and Lery Krut, he has long determined the image of the underground rap in Stuttgart Germany.
He will be signed by the newly founded Stuttgart label "Boulevard of Broken Dreams" in July 2011. Kay One and Geeniuz believe in the talent of the boy and want to get started together. At the same time, the "AP Millionärsclub" Crew is launched. Other members are Shindy, Safe & Blacklife. After differences, the paths of the artists are broken.
