The music club Jazz Republic has held concerts since 1997 pretty much without a break. It is mainly the concert dramaturgy that determines the character of the Jazz Republic and is unique in Europe and probably even the whole world. We cooperate with 30 top Czech jazz musicians, who as residential artists compose ad-hoc music formations performed at the Jazz Republic. Each concert is therefore special, because it will never repeat itself with the specific constitution and repertoire. This is our tribute to jazz music and its basic constructive process, musical improvisations.
