"Wergo offers this pair of new releases featuring two icons of contemporary American music, John Cage and Henry Cowell. . . . Sabine Liebner's collection of piano works by Cowell and Cage explores the period from 1912-1948 and documents not only the emergence of American experimental music, but also their teacher-student relationship. Amiable Conversation allows us to compare Cowell's piano pieces with Cage's to reveal common features that are as clear as the differences."
