With new innovative concepts, technology and multimedia, we are focusing on releasing high quality music and building up newcomers alongside with international guest artists.


We are not a kind of any booking agency, we are a growing family! With over a decade of experience focused on DJ management we are representing, developing, positioning and elevating DJs, live performers and singer & songwriters into the music industry and we are managing and creating international booking opportunities.


We provide full service management to innovative artists so they have time to focus on what they do best, music. Our focus is to help artists to develop theirselves and show up their real talent the best way possible. So we handle all the matters of an artist like booking, public relations, social media and many more.


Next to our labels we`ll also launch our own event series in form of label nights. Many people can come together in a peaceful and private atmosphere to laugh and to enjoy an unforgettable night and to collectively dance to the melodic sounds of our artists. We also give the artists a platform and in addition to book artists we like.
