D-Block & S-Te-Fan, also known as Diederik Bakker and Stefan den Daas, are a successful hardstyle duo from the Netherlands.
They began producing music together in 2004 and have since become known for their euphoric hardstyle sound. Prior to joining forces, both artists had their own solo careers, but they found the most success as a duo.

Some of their notable tracks include “Built This City” and “Music Made Addict.”

They have performed at various events such as Qlimax, Mysteryland, Thrillogy, and Decibel. In 2010, they were ranked #73 in the “DJ Mag Top 100”, establishing them as the top hardstyle artists of that year. In 2015, they released a track called “Beautiful World” under their new house alias DBSTF, but they still produce hardstyle music under their original name, D-Block & S-Te-Fan.
