Davor Sučić (Serbo-Croatian pronunciation: [dâʋor sût͡ʃit͡ɕ]; born June 7, 1961), better known by his stage name Sejo Sexon, is a Bosnian rock and roll musician, film score composer, actor and television director.

Their first recording, "Penzioneri na more idu zimi" (English: Retirees go to the seaside in the winter), was made for Radio Sarajevo in early 1981.

Sejo Sexon performed with Zabranjeno Pušenje around Sarajevo for two years before beginning to record material for a debut album during Fall 1983 in producer Paša Ferović's modest studio.

The shambolic recording process took seven months before the album named Das ist Walter got released by Jugoton in April 1984 in the small print of 3,000 copies, clearly indicative of the label's extremely low commercial expectations.

The second studio album Dok čekaš sabah sa šejtanom (English: While you're awaiting dawn with the devil) is released through Jugoton on June 11, 1985.

[4][5] In that time, Sejo Sexon and Ostojić worked on their solo record for Diskoton, but that studio album went unreleased due to the start of the Bosnian War.

In 1996, members of the sketch comedy show Top lista nadrealista pit orchestra such as Sejo Kovo, Đani Pervan, Dušan Vranić, and Samir Ćeramida had become the core of the renewed band.

The fifth album of Zabranjeno pušenje Fildžan viška (English: An Extra Cup of Coffee) is released through Dallas Records and Nimfa Sound in 1997.

On that project, he got an opportunity to collaborate with prominent musicians of different genres, such as: Halid Bešlić, Arsen Dedić, Lucija Šerbedžija, and the Mosque Choir Arabeske.

By the end of 2006, Sexon had begun to establish a supergroup Shaderwan Code (a law book of shadirvan), following a sort of a friendly match between the band Zabranjeno pušenje and the Zagreb Mosque Choir Arabeske.

On December 28, 2013, Sejo Sexon and Zabranjeno pušenje celebrated 30th Anniversary of the band with their fans on a concert in Skenderija, Sarajevo.

[21][22] Sexon and Zabranjeno pušenje performed live at the EXIT Summer of Love 2017[23][24] in Novi Sad, Serbia, and at the Belgrade Beer Fest in 2017.

[25] Sexon was working occasionally on the sketch comedy and variety television show Top lista nadrealista in-between 1984 and 1991.

[2] After re-union of Zabrenjeno pušenje in 1996, Sejo Sexon and Elvis J. Kurović had more than 300 occasions where then performed live Top lista nadrealista across Bosnia and Herzegovina, Croatia, Slovenia, Germany, Austria, Denmark and Switzerland.

In the late 1980s, Sexon wrote film scores for two TV mini series for kids directed by Timothy John Byford and aired on RTV Sarajevo.

[2] With Goran Bregović and Miroslav Mandić, he won the Golden Rose award for the best TV advert clip at Monterrey, Mexico in 1990.

In 2009, Sexon was a jury member together with Zele Lipovača, Davor Gobac, and Vinko Štefanac on Rat bendova (English: The Band Wars), a musical contest that aired on Bosnian television network OBN.

[2] They organized more than 80 benefit concerts across in Bosnia and Herzegovina, Croatia, Denmark, Germany, and Slovenia to raise awareness about refugees of Bosnian War.

In 2001, Sejo Sexon and his fellow band members from Zabranjeno pušenje took a part in a social responsibility project in which they organized music workshops for children and youth who were victims of land mines.

He thus enrolled at the University of Sarajevo's Faculty of Medicine, which he put on the back burner after starting to make a living through the band.
