unbestimmt (2020) for organ

Performed by Wolfgang Kogert on the organ of the Hofburgkapelle in Vienna, Austria. Released on the album ORGANO/LOGICS (col legno 2023) https://essl.at/records/organologics.html The piece draws its strength from the interaction between constantly changing chord structures, whose harmonic components are made more or less audible by slowly pulling out the stops.
