We hardly ever send a band for indoor functions at the White House. We will usually send a variety of groups for different parts of a function...flute/harp duet, string/piano quintet, chamber orchestra, strolling strings, dance band, solo violin, solo piano, jazz combo, brass quintet (rare), woodwind quintet. A concert or ceremonial band would be much too loud inside the White House...the foyer is much too live.
So 60% of the program wouldn't interest me.
I've played the Kennedy Center Honors reception a few times at the White House. This reception occurs before the honors ceremony at the KC. This year, Liz showed up very late and I didn't see her. I did see Levine pass by the orchestra. He listened for a while and paid some very nice compliments. We will often play a Mozart symphony. There was a time when we sent only one horn player in the chamber orchestra. It was the trombonist's job to play the 2nd horn part. I was able to sharpen my transposition chops by reading the various horn parts for these little played pieces...early symphonies of Mozart and Haydn. What great fun. How many professional trombonists get to play a Mozart symphony? I've been told I'm quite effective at making my trombone sound like a horn. It's quite simple...I just stick my hand in the bell and bust a lot of notes.
