Fredrik Engström discovered hip hop properly in high school and since then he has also been a faithful record collector. In the late 90's he also started to grab the mic after starting to listen to Looptroop Rockers. The group Irsta Kånektjon was formed and two tapes and a CD were released. After that Fredrik went solo under the name Osten af Mozzarella, today Osten af. With a playful and referential style, he has gained an audience outside of hip hop, despite being genre-true in his own listening.
