My Hans Zimmer story 

It started a long time ago. I think when the soundtrack to Batman - Dark Knight came out. I saw a video of Hans Zimmer talking about originality. He mentioned that he was looking for musicians who were exceptional in their approach to music. I got the feeling that I could be part of Hans Zimmer's team. I had no idea how his world worked. I reworked his songs and tried to get to him somehow. A guy from Slovakia who was interested in nothing but music.

Im on SubStack 


I don't know if you all know that I've been keeping a diary since 2005. Since I quit my job and stayed with my daughter on maternity leave, I have also published a book in the Slovak language. It was an important period in my life. It was impossible to go to work and be a full-time musician. 

Gradually I will publish these diaries on my Sub Stack profile. I write in Slovak and I translate the diaries using Deepl translator into English. So English won't be great, but you will be able to understand my feelings and observations. As we say in Slovakia "you can see into the kitchen"

New project THE BUZZFISH! 

This new project is planning its first concerts in November 2022. So far we can only reveal that it will be very loud!

New film 

For a week now I have been working on the music for a documentary about the Slovak director Dušan Trančík. I admit that I didn't know his work before. He lived a large part of his life under communism, which was characterised by endless censorship and bureaucracy. In the film, Dusan asks the question whether film can change the world for the better. My favourite director, Andrei Tarkovsky, asked a similar question. 

I look forward to seeing another worthy film directed by Erik Praus, one that does not give us an answer, but asks more important questions.

Music by Peter Gabriel. 

David was approached to record guitars for Jeremy Nesse's project doing new arrangements of Peter Gabriel's music. Several of Peter Gabriel's bandmates worked on the project, as well as a quantum of musicians from all over the world.  
You can listen to the track in which David plays in the link. 


Recording sessions with Thomas Newman.  


It was an excellent two weeks in Los Angeles. Quantum of great experiences and meetings. I met the excellent musician Rick Cox, who took me to the Thomas Newman studio, where we recorded a few hours of improvisation.


Paris RADIO!  

"Effusions, Extracts from the Notebooks" by Goliarda Sapienza

Around Goliarda Sapienza's Notebooks, the music of the trumpeter and the voice of the actress are perfectly tuned for a new creation imagined for the radio.

Music by Erik Truffaz, guitars by David Kollar

"The Art of Joywas given to me for my birthday a few years ago. Busy with so many things and with traveling, this book, of at least eight hundred pages (therefore heavy to carry), was in my suitcases each time. On each return, prominently on the shelf of my library. A place chosen among my most precious books. Those who filled me. The Art of Joy what a beautiful title! And yet I haven't read it yet. I started with the Notebooks and The Certitudes of Doubt. We have chosen these Notebooks to travel with you. Goliarda Sapienza's Notebooks recount certain stages in her journey, with her joys and sorrows. The exigency of his thought, the beauty of his writing, his outpourings resonate in me, and it seems to me that they echo each of us. As for The Art of Joy, knowing that her writing work took ten years for her to be satisfied with it, so no longer between two suitcases but in a sacred moment The Art of Joy will be my next recollection. In the meantime, with a joyful heart, with Erik Truffaz yet another great trip!
