In this section you will find the results of all the previous CLEs (Coordinated Listening Events) which have been held by the group. There is also a brief explanation of what CLEs are, and how they work, and also a copy of the 'CLE History', which shows a list of all the events which have so far taken place. The data for each new CLE will be added as and when it is available. And now that you know what a 'CLE' is, why not check out some of the results from our previous listening events below. All files are in .pdf format, and most are less than 180kb in size:

The CLEs are run by our CLE Coordinator, Brian Keyte, and you can find out more about it by contacting Brian at the following address:
