Indexi was a Bosnian and former Yugoslav rock band popular in Yugoslavia. It formed in 1962 in Sarajevo, Bosnia and Herzegovina, and disbanded in 2001 when singer Davorin Popovic died. Some of their most notable songs are "Plima", "Sve ove godine", "Svijet u kome živim", "Sanjam" and "Bacila je sve niz rijeku", which was later covered by many other ex-Yugoslavian groups, notably Crvena jabuka. Indexi formed in 1962, and their name was derived from the "Indeks" which was a students' grade log. They began by making instrumental covers of popular hits, but in 1967 started composing. They were known as the "Pioneers of Psychedelic Rock", and were inspired by many bands like the Beatles and Yes.
