I came across this video today and had two immediate responnses after watching:
1) It is a cappella, multi-tracked. Yet another example of how strong the contemporary a cappella movement is right now. For more on this movement, please visit my non-profit, the A Capppella Education Association.
2) The national anthem in minor is pretty cool sounding!
Sorry I've been so absent for the past few months...my teaching, conducting, and composing schedule has been intense. I'll be back soon with more, I promise!
