Rosa Papier, famed opera singer and teacher, became a major advocate of composer Gustav Mahler, even successfully lobbying for his appointment to the Vienna Court Opera. Michalek presents a well-documented and indexed view of correspondence between the two (and others) at the close of the 19th century and the beginning of the 20th. Universal Edition says, "The immediacy of this correspondence throws an incomparable light on the vibrant nature of a relationship in which professional and personal lives appear to mix freely."
