This is Five Pieces for Orchestra by Anton Webern. The five pieces for orchestra are less than five minutes long in their totality and never sound as though they're written for more than three musicians at a time. This is extremely personal music written by a minor master. Music does not get more private than this, and yet his music caused so many vituperative debates among the generations that followed. Hopefully, we'll all be able to recognize Webern to what he is - a composer with a highly private language that can never be imitated.
