4Light provided the technical production of Harmony of Hardcore and 7th Sunday Festival. Commissioned by Par-T, we took care of the disciplines audio, light, video, rigging and motion. 4Light was involved from the design process to make the technical translation and associated plannings. During this preparation process and the production, 4Light has the 3D drawings under its care, so that all described details are clear. This is also the starting point for programming and artists advancing. We look back at another successful edition!
