About Hanns Eisler: Hanns Eisler is probably best known for his long artistic association with Bertolt Brecht, and for the scores he wrote for films. The Hochschule für Musik "Hanns Eisler" is named after him.
A composer knows that music is written by human beings for human beings and that music is a continuation of life, not something separated from it.
Someone who knows only music, understands nothing about it.
