The ensemble that performed at my grade school strengthened my interest in jazz, so I wish could remember the band's name. I remember being impressed that jazz's improvisational nature applied not only to the music, but also to its concert banter. A percussionist had explained earlier how just about anything can be a percussion instrument. To demonstrate, he started humming a tune through a straw. When one of the other players was taking a little longer than usual to find a pitch while tuning, he asked the player, "Soda straw?" "No, thank you," replied the player.
Now, there's something you wouldn't expect to see at the symphony.
