Kottarashky aka Nikola Gruev opened the door to hitherto undiscovered spaces of Balkan music with his first album "Opa Hey!" in 2009. His approach of using a collection of sounds taken from authentic field recordings is quite similar to artists like Amon Tobin, the only difference being that Gruev found and recorded his sources in the Bulgarian countryside. Combining these, he initiated a tribal digital dance music that went far beyond either the mash up culture of contemporary global producers or the art collages of modern sound architects. He simply amazed with compositions that are extremely complexly woven, yet at the same time catchy, and full of joy or melancholy. At the time however, Kottarashky was unknown, even within his local scene in Bulgaria. It was all the more unbelievable that this dude, who was actually a full-time architect, was producing outstanding tunes and unique rhythms such as these in his back office that were completely unconnected with any popular scenes.
