The album contains the entire organ works by Karlheinz Essl, composed between 1986 and 2021 and recorded by Wolfgang Kogert on the Kuhn-organ of the Hofburg Chapel in Vienna. It is the result of a long-term friendship and collaboration, but above all a teamwork that is entirely dedicated to the fascination of this instrument. While Karlheinz Essl draws on well-known songs in his compositions and is inspired by elements from early music to the avant- garde, Wolfgang Kogert interprets the pieces sensitively and with virtuosity. The mezzo-soprano Anna Clare Hauf can be heard as a guest musician. The title “ORGANO/LOGICS” suggests treating the album as a kind of study that opens new approaches to the “queen of instruments” on a compositional and technical level.
