Czech Philharmony with Jazz at Lincoln Centre Orchestra at Prague's Open Air Concert



A Unique joint performance by the Czech Philharmony and world famous jazz promoter - Wynton Marsalis, alongside his Jazz at Lincoln Centre Orchestra, was held within the traditional Open Air Concert at Prague Castle. In what is becoming the norm, KV2 Audio was chosen to provide the excellent sound system.

Marsalis first tuned the audience with three standard pieces by Duke Ellington and then both orchestras played in unison, Marsalis symphony conducted by Wayne Marshall. This had to be unfortunately terminated just before its end due to the sudden adverse weather conditions. However this piece acted like a history guide through various forms of swing. It needs to be highlighted that members of the Czech Philharmony were the absolute equivalent companions to the star performer, especially trumpets and clarinets.

Unlike previous years, when promoters chose the KV2 Audio VHD2.0 Large Format Point Source System, this year the new revolutionary system VHD5.0 was utilized. It is a matter of course that the whole acoustic chain was kept analogue, including mixing consoles Audient Aztec 48 for the orchestra and Audient Aztec 32 for the jazz ensemble.
