Because of the war in Yugoslavia, Divlje Jagode stopped performing and therefore Žak has started working with the Slovenian band Mary Rose.

In the beginning of 1994, Žak has contributed on the joint project of the famous European rock bands Helloween and Gamma Ray.

In 1995 and 1996 he worked as an instrumentalist and vocalist on two albums of Slovenian band Turbo, called The Power Of Metal and A Glimpse Of Home.

Due to the urge for making original authors music, he and guitarist Eki Alilovski refounded Mary Rose in 2004.

In 2006, he also founded a jazzy band Norne with famous Rijeka's vocalist, where Žak is playing a bass guitar.

In 2013 he joined Slovenian heavy metal band Black Diamond,[1] after the release of their first album Last Man Standing, on which he sang most of the songs.
