Bach's Brandenburg Concerto with Natural Trumpet

Recently I played the 1st movement of J. S. Bach's 3rd Brandenburg Concerto.  Since it's scored for all strings, I thought I'd give you a sample of Brandenburg No. 2 with woodwinds and brass in a period instrument performance by the Freiburg Baroque Orchestra. Note the natural trumpet, recorder, and older style oboe. http://www.youtube.com/watch?v=6jtk4ETAx8g
