It is strange to see, when you search for Rock Music in Serbia or more precisely when you look for "Serbian Rock Bands" with help of greatest Search Engine in the known universe, and that will Be Google for sure - well it is strange selection of musical groups from this part of the world, from this hellhole we also call Serbia. We can also type bands from Ex-Yugoslavia, we will find somewhat similar results.
So what I do find strange is: some big mistakes like that first result on the left - Ekatarina Velika, also known as EKV. They played much more than what we see in this carousel - they were very much alive and kicking in 1985 and years after that till they tragic demise in 1994. This is when Milan Mladenovic, the leader and Frontmen of EKV died. Some other sources online are more accurate abot this magnificent art group "Активни период, 1982—1994. Место оснивања, Београд, СФРЈ." that is Wikipedia
