We always put the marathon's music quality in front. This is a priority for us. We invite the best DJs from all over Europe and the best among Polish DJs.
What is most important to us is the dance flow during the marathon, the involvement of most dancers, which we supply by balancing the dancing roles 50/50% (leader/followers). 
The music system in AGORA (the venue) produces an exceptional sound quality which can be put to a great advantage even with old music records, such as some of the tangos.
We also care about the "ronda" and try to arrange the dancing hall to facilitate the dancing.
