I was cooking again today (yes, you are starting to notice a pattern in these posts) and listening to a Gaither hymns CD (yep, that's another pattern). This one included the Martins singing "He Leadeth Me." They have the most amazing a capella sound.
I've seen them sing the Doxology in person at a Christmas concert a few years ago. It brought the house down. Here is that number:
And this is a great, fun song for Epiphany, which happens to be the season we are in. (Sorry that there's an ad at the beginning, but it's a good, high-quality video.)
I don't know why I don't own an entire CD and/or DVD of the Martins. I should rectify that.
