The collaboration of J.K. and R.H. it lies in mutual understanding, where it is not about jazz standards, but a more rock-like concept of own compositions and texts. Among other things, Roman is an Adventist pastor. He "preaches" well, sings and acts, and with J.K. they are a good duo who also understand each other in rap and in communication with the audience. Together with other colleagues, they recorded the CD SMRT STANDARDIZMU released by Multisonic 2014 and the CD A TAK SI JDU.. by Supraphon 2016, including a video clip on YouTube.. /the opening track A tak si jdu../. Hopefully this will be enough. Next year I will be 80, so I will greet the Smoking Rabbit probably for the last time, but with great gusto... and the audience in Brno will hear what they haven't heard yet
