Develooper (CZ) is a musical group of composer and multi-instrumentalist Petr Wajsar, which combines a love of electronic dance music with a love of classical and acoustic music. The current form of the project is the result of an effort to synthesize techniques that allow music to be created on the spot with minimal use of pre-recorded material, so that the music is a real live concert, albeit with the use of the most modern technologies. The main protagonist uses VR glasses that allow him to create music using gestures and movements, so that listeners can be direct witnesses of how the music is created. The contrast to the technological aesthetics is the beautiful and natural sound of Anna Wajsarová's clarinet. In addition to musical elements, the show is complemented by a distinctive visual projection, thanks to which short videos also become part of the music, which are rhythmized with the help of VR glasses and used as another musical instrument. This set is suitable for dance or experimental electronic music festivals, but also for multi-genre festivals and, of course, for clubs.
