Not'under Stein a.k.a. Stein dj /Metropolis::booking/ was born in 1984. He was interested in music since he was a kid, but had a chance to start dj-ing in the beginning of 2004. Then he founded the project "Keep It Underground" together with his friend and colleague Bineff. That happened in a moment when house music in Bulgaria was gaining popularity along with the leading role of music fading away, it all had become fashion, drugs and fancy places. So "Keep It Underground" was about keeping it all about the music! Stein's initial style varied between Tech and Techno, pumping with a lot of vocals and percussion, and gradually developed into minimal house, tech-house and tribal beats all of the time corresponding to the newest records on the scene. In 2009 Stein and a George West, a friend and fellow dj, established an organization for music and party events called "Underground Society". They joint their talent and hard work in order to become one of the most promising young producers on the Bulgarian music scene. In 2011 Stein joint to METROPOLIS booking - the pioneer of the electronic music in Bulgaria and one of the best booking and promoting agency. He play with the biggest names at the biggest stages and events. The future will show…to be continued...
