Kalle Karvanen, a DJ, promoter and a record label manager, who freaked out to electronic dance music in the mid 90's, started making own tracks and collecting vintage analogue gear in 1997, then deejaying in 1998. He then launched Skeletor Records in January 1999 in order to give young and fresh finnish talents an opportunity to release their own music. Skeletor Records came to it's end in December 2002 after releasing six records and organizing some of the most memorable events. Nowadays Kalle is busy with his electro label, X0X Records.

In playing records Kalle isn't stuck to one particular genre. He plays electro, techno, italo, acid and acidhouse tracks, not forgetting his past in hiphop and big beat. His mixing style is tight and mindblowing and this also got him to a situation where he was the first finnish who participated to Red Bull Music Academy in 2001. Kalle is also a part of a liveact called Technical Directors, which idea is to play 110% live sets with vintage gear and create every sound in front of the live audience, mostly with legendary Roland x0x-series drummachines and synthesizers. Besides of this all Kalle is also producing his own music, which is an ever-lasting constructionyard.
