Between Mozart and Beethoven, it's hard for me to decide what to recommend. Most people I know have never heard the WHOLE 4th movement of the Beethoven's ninth symphony. Most people have only heard the chorus singing the theme or little excerpts from the fourth movement. It is a great experience to see the whole thing. It's just plain AWESOME! I love the music from the opera buffa, "The Marriage of Figaro" by Mozart. I also love the 3rd movement from the Piano Concerto no. 21 by Mozart. I have a recording of this with Alicia de Larrocha at the piano accompanying the English Chamber Orchestra. There is so much music to decide from. But some people have different opinions.
