Despite the emergence of brain-computer interfaces, social applications of this technology wherein users interact with each other are infrequent. Thus, we develop a novel system consisting of a multiplayer virtual reality live concert in which the brain activity of the audience is used to elicit visual effects, based on the $\beta$/$\alpha$ ratio signal obtained from the single-channel electroencephalogram (EEG) recorder. In this way, the system interconnects users through neurofeedback that can potentially be used to cause a 'sense of unity' between users. In this work, we introduce the configuration, implementation and specifications of the system, proposing a local configuration and a client configuration. Function testing of the system performance for generating visual effects and quality control of the signal is conducted. A preliminary study to test the system is also shown, and the $\beta$/$\alpha$ ratio signal and questionnaire are briefly analyzed. We propose the usability of the system for future research on the influence of music and emotions on group interactions.
