Every year, the Euroradio Jazz Producers put together a European jazz big band under the name of the Euroradio Jazz Orchestra (EJO), a project that can trace its roots back to 1965. Each EBU Member may send one musician under age 30 to perform in public with the EJO, with two Euroradio Public Jazz Concerts organized by the host broadcaster. At least one concert is always recorded by the EBU host broadcaster, who is responsible for the rehearsals as well as its logistical and promotional planning.

The 2019 EJO will be hosted by ORF (producer: Andreas Felber) and coordinated by the Chair of the EBU Jazz Producers, Hugo Sekoranja (SIRTVS). Under the conductor/composer Christoph Cech, the EJO will give concerts from 16 to 19 October in Graz, Vienna, Linz and Salzburg. The Jazz Producers will meet in Vienna on Friday, 18 October.

This year, Radio Slovenia, the ARS programme, selected jazz vocalist Ajda Stina Turek to participate. Last year she presented the Sonder EP with musicians she brought from Boston. The recording was broadcasted by European radio stations as part of the EBU International Jazz Day, and positive responses also led to the selection to participate in the orchestra.
