There are many more Websites that can be interesting and useful for (young) managers, but our time within the STAMP project was limited.
You will find a number of links under the other sections such as Online Resources or Training Opportunities.
We also recommend to music managers to check out the Websites of the International Music Council, the European Music Council (and the list of their member associations) as well as the Website of Culture Action Europe.
And of course you should check out the STAMP Database on http://www.stamp-music-training.org/
The European Choral Association – Europa Cantat has collected a list of Websites which are useful for choral managers or choral conductors: Weblinks for Conductors and Managers 2014
