The Sinj Meeting of Amateur Rock Groups (S.A.R.S.) is an alternative culture festival organised by the Sinj Cultural Urban Movement (S.K.U.P.) association. Held annually at the end of July, the festival has been running for over ten years now. It all started in 2003, with the original purpose of promoting amateur rock groups from all over Croatia. Over the years, however, famous groups from both Croatia and abroad have played at the festival.

As a result, Sinj has been visited by large audiences not only from nearby places, such as Imotski, Split and Knin, but also from more distant places. The following groups have so far performed at the S.A.R.S. festival and other music events organised by the S.K.U.P. association: Let 3, Dubioza kolektiv, Dječaci, Gužva u 16-tercu, Massimo Savić, T.B.F., Gustafi, Raising Dream, Cold Snap, Father and many others.

Apart from music events, the S.K.U.P. association has also organised a number of accompanying events: performances, literary evenings, showings as well as workshops on different subjects. Promoting amateur rock groups and providing an opportunity for audiences to hear well-known musicians play in Sinj has not been the only aim of the S.A.R.S. festival. Moreover, the festival's very purpose has been the promotion of the Town's spirit of culture and tolerance.
