Here is a Telemann duet I just did this weekend, with a twist that it is the same video - twice presented with a one second delay.
This cartoon video is a Video Poster Board to explain about the trumpets in the Bible and more specifically, "Did they have valves?" Created by John Francis using Powtoons. Content comes from my thesis titled, "Trumpets in Scripture: The Representative Voice of God."
Mauricio Solis, violin; Eddie Epperson, piano; Steve Tucker, vibes; John Francis, trumpet at Beacon Hill Baptist Church, Somerset, KY, USA
