If you ever need to raise money to build or repair a monastery, ask the Serbs how to do it. I've seen at least two different videos from this project referenced on different Orthodox blogs. Apparently a bunch of professional musicians and performers contributed to this fund-raising effort, to restore a medieval Serbian Orthodox monastery. I don't know more than about two words in Serbian, but if I weren't already interested in Orthodoxy, I'd like to think watching these music videos would have got me interested.
I definitely recommend the one I saw referenced most recently, which features prominently the Slavonic Easter greeting: Christos Voskrese! (Christ is risen!) But as far as I'm concerned, they're all (all that I could find online anyway) worth watching.
