For four years in a row now, 4Light has been in charge of the technical production of the UNTOLD Festival and taken care of the disciplines Audio, Light, Video, Rigging and Stage Management. Aside from the size of the stage and the large diversity of the acts, the stadium itself constituted a major logistical challenge with a detailed logistical planning. The stadium only has one entrance and is surrounded by a very busy tramway.

To be able to change all the acts, a large festival roof with backstage tents was constructed. The diversity of the acts made for many changes in the setting in the stage roof, in which five guest trusses were standardly incorporated.

The day programme of such a large festival consists of receiving the visiting acts and setting up the materials brought by the artists. To be able to facilitate and organise this properly, a group of staff divided over multiple shifts is on hand 24/7.
