For those who do not know this work you can listen to extracts of the Avie
recording here:

http://www.ludwigvanweb.com/navigation/1,1270,6-1-cd-822252000320,00.html

You can always restart an extract from approximately where the previous
one left off to build up a picture of the whole work (each extract is
limited to 15% of the track length or a minimum of 30 seconds)
