Query: Christian is the world's best trombone player!

I thought the cd was good. But I did not like U-tangia Na; it showed man's sinful ideas of music, which is not good: it is chaotic, self-centered, and it doesn't even really make sense. I really liked Alma Ingrate! He uses a sackbut on this one, which used to be the first trombone, as we would call it now. He also uses Yamahas, Conn tenors, and a Conn alto trombone. If you're just starting to enjoy the trombone, or if you'd like to be introduced to this ancient but melodious instrument, this cd is for you! You'll be amazed that you are hearing a trombone; you will think it is a French Horn. Try it!
