Hanz Sedlář was born in Kroměříž in 1989. He is a drummer who also writes music for a symphony orchestra or chamber orchestra. He specialises in sound engineering for a drumset and orchestra. Since he was a little boy he knew he would be a musican. He started to play piano when he was 6 years old. After few years he started to try and improvise, that's why he started to compose. Just one year before starting the Music Conservatory in Kroměříž he decided to start playing the drums. For that reason he did not want to study piano at the Conservatory. After joining the Conservatory he put together an orchestra, which he organised from a group of people that he knew from the Conservatory. As time passed he wanted to bring together two different genres of music. 

He brought together his drumming and composing and this is how the Drumphonic project began. This would not have happened without the cooperation with great guitarist and co-author David Uher. Hanz's next big plan is to make a project Drumphonic with live symphony orchestra, because he writes his play-along songs like classic score for orchestra. 

In 2019 year Hanz composed arrange for big symphonic orchestra. This big project, which Hanz make for two czech popstar conducted with five Czech philharmonic orchestra in 5 big concerts halls in Czechia. 

Hanz works at his dream now. He want make a big show with his own symphonic orchestra with video animation cooperation.
