Open your mouth and sing “Ahhhhhhh”
This is truly cool. My friend Z pointed me towards a Podcast dedicated to college acappella: Acappella U.
It’s a slow download, but check out the first episode — the group “Off the Beat” does a rendition of “Don’t Stand So Close to Me” that is absolutely outstanding. This is great stuff.
And if you like what you hear, I suggest you take a look at the BOCA CDs.
