Professor John Thwaites (Head of Keyboard at Royal Birmingham Conservatoire of Music) and his quartet colleagues talk about the research culminating in their landmark HIPP recordings of the Brahms piano quartets in Viennas Ehrbar Saal on three different pianos of the period. The talk will discuss evolving string and keyboard playing and performance styles during the course of the 19th century and will include audio-visual examples of vintage recordings.
