Thomas Jepsen is one of the music programmers for North Europe's biggest festival, Roskilde, where he focuses mainly on hip hop, indie, alternative, and electronic music. Roskilde has been a non-profit festival since 1971, emphasising environmental and cultural change through their work with donations. With more than 175 acts playing at the festival, it is always a formidable balancing act to ensure that the program involves all kind of sounds.
