While I am still getting pictures and video together to make a post about what I actually did last week at the SOLA conference, here is a video of the Te Deum from last Thursday's Matins service. It is taken from The Lutheran Service Book, page 941, "We Praise and Acknowledge You" This was all put together by talented musicians who had about 3 days to practice. There is no CD or backing to this hymn.
This video was taken by Hannah Adickes. I recommend minimizing the window and just listening to it.
