I give Rossko 2 thumbs up! I highly recommend his services as a producer, composer, remixer, songwriter and mix engineer."

"Rossko is among the most qualified sound professionals around the globe in the field of pop and dance music. I had the pleasure of collaborating with him for more than ten years, creating together most of the material in Deep Zone’s first five albums. Together we changed the sound of the contemporary Bulgarian music, building up high standards. With tracks like “Ela izgrei!” and “I feel like” we started a new era in dance music which has been evolving ever since"

"When I need a remix, I always turn to DJ Rossko, because he is the best there is in Bulgaria. I’ve asked him recently to produce as well the music arrangements to some of our new songs and I must say that I definitely find his arrangements phenomenal. It is a real pleasure working with him and listening to our production in the clubs."

"Working with Rossko has always been a great pleasure for he certainly knows how to make artists feel good and give their best during the recording sessions."

"I am glad that my first professional steps as a songwriter and beatmaker brought me to Reptilla Studio where I have become a regular thanks to Rossko’s expertise, loyalty and creativity."
