In 1961 the fair hosted two European sports championships: 1961 European Amateur Boxing Championships and, few months later, EuroBasket 1961. Both were held in the Hall 1. The same hall hosted the first major concert of the "youth culture and rock and roll" in Yugoslavia in 1966, with over 100 bands. Since then, the hall became a favorite venue for the "urban musical guerrilla", but also for the popular mainstream rock musicians. Concerts were held by Ekatarina Velika, Yu Grupa, Bajaga i Instruktori, Riblja Čorba. Foreign musicians include Eric Clapton (in 1984), Iron Maiden (1984, 2007), Deep Purple (2003, 2006), Alice Cooper, Kiss, Duran Duran, etc. Occasionally, Serbian folk singers were also performing in the Hall 1, like Džej Ramadanovski (1992; 30,000 spectators).
