The Loudest Festival on earth, where living loud is the only standard.

What started as a passion to gather the HARDER STYLES minded crowd in an outdoor event in 2002, grew to be a MASSIVE THREE-DAY FESTIVAL in the Netherlands. Decibel outdoor has become THE LOUDEST CITY ON EARTH, for those seeking the NEXT STEP in their craving for the Harder Styles. Every year in August we come together with 100.000 Harder Styles fanatics and hundreds of artists from talents to heavyweights. Always connected, always on the move and ready to LIVE LOUD!
