Born Alija Islamović in Bihać into a Bosniak family from the nearby village of Sokolac where he'd spend the first two and a half years of his infancy, the youngster grew up with an older brother.

In addition to Bihać, Bag performed in Prijedor, Drvar, Sanski Most, and Banja Luka, earning decent money.

After he served the army, Sead Lipovača, lead guitarist and founder of Divlje jagode, invited him to join the band.

The start with Divlje jagode was very difficult, but it eventually paid off as the band became a very successful hard rock act throughout many parts of Yugoslavia.

Eventually, when everything failed, Divlje jagode fell apart and Islamović returned to Bihać and decided to get a traditional job and quit music.

Bregović reportedly invited Islamović to join the band mainly for his healthy lifestyle (he allegedly stated that he had enough of drunkards and drug addicts).

He returned home in order to cure a kidney problem he developed on the road, forcing the cancellation of the rest of the tour.

In between his work with Radić, in 2005, Islamović took part in three large farewell concerts with Bijelo Dugme in Sarajevo, Zagreb and Belgrade.

He also played rhythm guitar and sang in the band "4 Asa" with Vlado Kalember, Slavko Pintarić "Pišta", Rajko Dujmić, and Jurica Pađen.

In October 2006, Islamović joined Željko Bebek and Mladen Vojičić Tifa in a Bijelo Dugme tribute band called "B.A.T.

After a successful show in front of more than 10,000 people, the entire tour was planned, being later on performed in Europe and the United States, with Islamović and Bregović as the only members.
