During april and may, enjoy the magic Mathias Heise creates with his harmonica. Accompanied by the Tivoli Ensemble, his tribute to the great Swedish jazz tradition will interpret pieces by Cornelis Vreeswijk, Jan Johansson, Monika Zetterlund as well as his great harmonica-playing colleague Toots Thielemanns who, despite his Belgian citizenship, was almost a Swede for long periods.
