Discoballs is one of the last surviving bands from the first wave of bands playing in Czechia in the second period. At the same time, it is the band that has played at Mighty Sounds (apart from Mighty stalwarts Fast Food Orchestra) the most times. Discoballs will celebrate 20 years of existence together with the festival, and on this occasion, former member and our colleague Vítek will join them after several years. A special occasion calls for a special lineup!
