Milana’s Broš Chamber Ensemble of Free Dance (Komorni Ansambl Slobodnog Plesa – KASP) was known for offering a radical response to traditional forms with improvisation, challenging established dance positions and norms through direct, unstructured movement exploration, while extending practices to non-professional dancers and presenting them in non-theatrical spaces. The performance Event 13, which debuted at the disco club of Student Center in Zagreb, in 1975 and was later presented in other unconventional, underground spaces, is marked by all the specifics as mentioned earlier.Starting from the challenging dynamics of club environments, where loud music often creates a sense of isolation and aimlessness, hindering interaction among people, the performance begins as the audience enters the space, where the performers engage in a near-ritualistic act of passing a ball to one another. The performers then form two opposing lines, reinforcing the linear movement of the rolling balls and creating a dynamic of horizontal communication, and contrasting directions. One performer disrupts the group of aligned bodies, knocking them down as they slowly rise again. The performance concludes with a free dance, inviting the audience to participate, which they would usually do.
