TubeNet

I found these interesting videos on YouTube today showing, in the first video, a rehearsal of a small post band and in the second video the huge massed band performance. I wish I could hear a translation of the band director in the first video... And to make this fit for TubeNet consumption , what kind of rotary tuba is being used in the first video?
