This is when the band began to disregard Bebek musically. In keeping with the Canned Heat-inspired boogie rock sound favoured by Vukašinović and Bregović, the two made Bebek stop playing the rhythm guitar reasoning it's no longer fashionable. Bebek also had trouble adapting to the new material vocally — he'd sing the intro on most songs and then step back as the other three members improvised for the remainder of songs. After being a key band member only months earlier, Bebek was seeing his role gradually reduced. It was more than he was willing to take and in the fall of 1970, he left Kodeksi to return to Sarajevo.
