RTE as well as providing TV,Radio & Web content also has a "Peforming groups" section. There are 5 groups and some 150+ costly professionals associated with them.
RT - Orchestras
The flagship of these groups is the National Symphony Orchestra, its ~90 players are dedicated to classical music and perform regularly in Dublin. Personally I enjoy classical music but find it ridiculous that the State subsidises the sector so massively. Ironically(?) Ireland's only world class classical group, The Crash Ensemble, is outside the RTE studios
