Background music to do PowerPoint to. I love these guys, their new album isn't my favorite, but my FAVORITE song is on here at right about 29 minutes if you want to skip ahead.
They're called the Ditty Bops, I've seen them live twice now and they're interesting. It's a little bit of folk, a little bit of vaudeville and I don't know what else other than gorgeous harmonies. Found it here, there's another one there too if you like this one.
