I would always be interested in attending a concert, and would be more concerned over the programme content than the level of the band. I've taken advantage of a number of the free concerts given by bands in the London colleges, either student groups or bands affiliated to the colleges, and these often feature quite adventurous programming, such as the London premiere of "The Trumpets of the Angels" last Friday.
I'm far less likely to turn out, either as a paying audience member or for free, if there are no programme details given, or if it is packed with run-of-the-mill potboilers and film music. Of course, a properly planned programme of good movie themes is another matter entirely :wink:
