I'm trying another Google map version, let me know how this works out!
This is a map of the majority of the ensembles listed on the Amateur Orchestras pages, but laid out using Google maps so that you can find organisations in your area. Simply use the zoom control and drag the map around to zero in on the area you are interested in! In general the location represents where a particular ensemble REHEARSES on a regular basis.
The type of ensemble is indicated by the colour of the dot, click on a dot to get further information:
Concert Bands (brass and wind)
* I don't update the map quite as frequently as the main data pages, so the information may be a little out of date.
