I've been meaning to do this for a couple of weeks and just haven't.
My parish has, since 2002, sponsored a Chamber Orchestra festival in late January. We are blessed with fantastic acoustics for such music, and have been fortunate to be able to structure the finances so that the events pay for themselves, enabling us to offer this outreach to the community, in the tradition of St Martin's-in-the-Fields, London.
This year we commissioned an original work from local composer Max Simoncic. Our music director let him know what resources were going to already be on the stage for the previous work. He had access to those instruments, plus the organ. Mr Simoncic came up with a delightfully fun piece called, appropriately enough, St John's Celebration. Click here and you should be taken to a My Space site where an mp3 recording of the work will start playing automatically. (Note to Robyn: Some nice horn parts.) It's not a professional recording (it was done on my handheld digital voice recorder), but it's respectable.
