Some gracious person uploaded one of the Rich Matteson/Harvey Phillips Tubajazz concerts to YouTube. It's from one of the US Army Tuba-Euphonium conferences in the mid '80s, perhaps. Rich and John Allred play some scorching solos in this concert. I think this group demonstrated that the euphonium and tuba have a place in jazz and does not need to be relegated to novelty or New Orleans jazz music. If you happen to know what model euphonium Rich is playing at this concert, please feel free to chime in. He's not playing a King 2280. However, Buddy Baker is playing a 2280, who's standing next to Rich in the second row.
