Under the title Flaschenpost für Jazzliebhaber, Kulturabdruck places the concertos of Zimmermann (1954), Gruber (1999) and Eötvös (2002/2016) side by side and follows the jazz that runs through all three — from the spiritual Zimmermann condenses into a hymn against racism to the “message in a bottle from my world to jazz lovers” Eötvös made of Jet Stream. Worth hearing several times over, the reviewer concludes.
