I don't think I have ever mentioned it before, but my wife and I own a tavern in here in town and once every couple of months or so we have live bands come in to play.  When they do I bring my camera along, of course.  Aside from the regular shots I take to display on our bulletin board afterwards, I also take some wilder, more experimental photos.  In these, my attempt is not to shot musicians or crowds, but to capture music if that makes any sense.  
Let me know if you think I am at all successful.
