On stage, we have Aya on vocals and guitar and Pablo on drums. They play their songs but it’s mostly improvisation. Before the song, a participant, in the public, positions himself on the dance mat style Dance Dance Revolution with the 4 arrows in cross. When the song begins, the movements to be performed with the feet are displayed on a screen to the rhythm of the bass drum of the drum set on which a piezo microphone has been installed. The more the rhythm accelerates, the more complicated it becomes to keep the rhythm of the dance steps to realize. At the end of the song, the score achieved by the participant is displayed and the reward for the performance comes out of a big mouth on a conveyor belt: makis prepared by Aya herself.
